Russia has told the UK it must send home "just over 50" more of its diplomats in a tit-for-tat row following the nerve agent attack.

Russia has already retaliated against Britain for the UK's expulsion of Russian 'intelligence agents' by ejecting 23 British diplomats over the poisoning of Sergei and Yulia Skripal in Salisbury.

On Friday, the UK's ambassador to Moscow was told London had one month to cut its diplomatic contingent in Russia to the same size as the Russian mission in Britain.

On Saturday, Foreign Ministry Spokeswoman Maria Zakharova said that meant Britain would have to cut "a little over 50" of its diplomats in Russia.

"We asked for parity. The Brits have 50 diplomats more than the Russians," she said.

It comes after Russia claimed UK authorities searched one of their planes at a London airport in what they called a "blatant provocation".

The Metropolitan Police denied the force had inspected an airbus that had landed at Heathrow having departed from Moscow.

It said: "We are aware of a story circulating on social media. Please be advised that Metropolitan Police are not conducting a search of an Airbus inbound from Moscow at Heathrow."

The Russian Embassy in the UK said in a statement: "Today, we have witnessed another blatant provocation by the British authorities.

"Border Force and Customs officers have searched the aircraft that was conducting the Aeroflot flights 2582 / 2583, Moscow - London - Moscow.

"This kind of event is extraordinary."

They also alleged British officials had tried to search the plane in the absence of the crew.

"After an Embassy officer arrived at the airport, long negotiations were conducted that allowed to ensure the right of the captain to take part in the search," they added.

"After the search was over, the British officers refused to provide any written document that would specify the reasons for their actions, their legal foundation and their outcome.

"Our attempts to get in touch with the Foreign Office in order to clarify the reasons of the inappropriate behaviour of British officials did not bring fruit. The Embassy has sent a diplomatic note demanding the British side to provide explanations of the incident.

"Of course, we will carefully analyse what has happened. At this moment, we have no other explanation but that the incident at Heathrow is in one way or another connected with the hostile policy that the UK government is conducting with regard to Russia."

The news comes as Russia continues to expel other foreign diplomats in a tit-for-tat response to countries across the world sending home Russian diplomats in solidarity with Britain following the nerve agent attack in Salisbury.

Russia faces mass expulsions of its diplomatic staff around the world, with more than 150 sent back from 25 countries, and NATO.

Ambassadors from a number of other nations, including Germany, Italy, Poland and France, were also summoned by Moscow's foreign ministry.

Ms Skripal is understood to be conscious and talking having been poisoned with novichok while visiting her father in Salisbury.

Police are treating the attack as attempted murder.

Mr Skripal, a former Russian spy, has been in a critical condition since 4 March.</s>The Russian embassy has accused British authorities of "another blatant provocation" after an Aeroflot flight was allegedly searched by Border Force officers at Heathrow.

An embassy official suggested that the jet, which had arrived from Moscow on a scheduled return trip, had been searched in connection with the diplomatic crisis over the Salisbury spy poisoning.

The row intensified on Friday after the Kremlin ordered Britain to reduce the number of diplomats in Moscow down to the same amount that Russia has in London.

It came as ambassadors from more than 20 countries were called into the foreign ministry in Moscow to be told of the latest wave of retaliatory measures being imposed.

As the crisis notched up the Russian embassy in London said British officials had searched an Aeroflot jet that had landed at Heathrow from Moscow.

According to an embassy officer Border Force and customs officers at first tried to search the plane without the crew, although the captain was eventually allowed to be present.

"Today, we have witnessed another blatant provocation by the British authorities," the official said.

"Border Force and Customs officers have searched the aircraft that was conducting the Aeroflot flights 2582 / 2583, Moscow - London - Moscow. This kind of event is extraordinary."

The Metropolitan Police, which is coordinating the investigation into the poisoning of Sergei Skripal and his daughter Yulia, denied it was part of the search.

The Russian embassy said it had complained to British counterparts and called for an explanation.

The UK expelled 23 Russian diplomats in the wake of the poisoning of Mr Skripal, 66, and his daughter Yulia with the nerve agent Novichok.

Laurie Bristow, the UK ambassador in Moscow, was among those called into the foreign ministry in Moscow on Friday.

He told reporters: "It is important to bear in mind why this crisis has arisen in the first place.

"It's the use of a chemical weapon on the streets of the United Kingdom that has threatened the lives of a number of people in my country.

"We asked certain questions of the Russian state and have still not received adequate answers."

Russia has told a number of countries - including Ireland, Germany, Italy, France, Spain, Finland, Poland, the Czech Republic, the Netherlands, Norway and Australia - they must send home the same number of diplomats as they had ordered to leave their nations.

So far, more than 150 Russian diplomats, some of whom are suspected spies, have been told to return home by the UK's allies.

The Russian Embassy said on Friday it "insists" on the right to see Ms Skripal, 33, after it emerged on Thursday she was improving rapidly.

She spent three weeks in a critical condition after being exposed to Novichok on March 4.

Ms Skripal's father remains in a critical but stable condition in hospital.

On Friday afternoon, the Russian Embassy published a list of 27 questions it claimed it had for the British authorities over the treatment of the Skripals.

The list included demands to know the exact nature of their condition and how they were being treated, and whether British doctors' approach "helped or harmed" the Skripals.

It also claimed Mr Skripal's niece had been inquiring after her uncle's health but that she had been ignored by the Foreign Office, and wondered why no images or footage of the Skripals alive in hospital had been published.

Scotland Yard believes Mr Skripal and his daughter, who was visiting him from Russia, first came into contact with the deadly chemical at his home.

Detailed forensic testing revealed the highest concentration of Novichok was found on the front door.

The vast attempted murder investigation continues to unfold in the Wiltshire city, most recently leading police to cordon off a children's play area at Montgomery Gardens.

Detectives said traces of the nerve agent had been found at some of the other scenes where investigations had been carried out, but at lower concentrations.

Efforts will now focus in and around the address, and specialist teams will step back from some of the other areas investigated over the past few weeks.

Mr Skripal and his daughter have been patients at Salisbury District Hospital since they were discovered unconscious on a park bench close to The Maltings shopping centre nearly four weeks ago.

Wiltshire Police Detective Sergeant Nick Bailey, who was also exposed to the nerve agent, was discharged from the hospital last week.</s>Russia authorities said that action would be taken against the UK if an answer was not given regarding the aeroflot search.

Russia’s ministry of transport said Moscow would demand an official explanation from Britain for why a Russian Aeroflot passenger plane had been subjected to a search at Heathrow airport on Friday.

The Russian embassy in Britain complained about the search at the time.

On Saturday, the Ministry of Transport said it wanted to know what had happened. "If there is no explanation, the Russian side will deem the actions towards our plane as illegal and also reserve the right to take similar action against British airlines," it said in a statement.

Meanwhile the British government is considering allowing visits to Yulia Skripal, who is recovering in hospital after being poisoned along with her father, a Russian ex-spy, in a nerve agent attack blamed by Britain on Russia.

"We are considering requests for consular access in line with our obligations under international and domestic law, including the rights and wishes of Yulia Skripal," a spokeswoman for Britain's foreign ministry in London said.

The Russian Embassy in London said in a tweet on Friday that "we insist on the right to see" Skripal, a Russian citizen.</s>Russia authorities said that action would be taken against the UK if an answer was not given regarding the aeroflot search.

Officers allegedly boarded the flight "without grounds" shortly after it touched down at London Heathrow airport at 3.37pm local time on Friday. Shortly after landing, police "insistently" asked passengers and crew to leave, but the pilots refused, according to multiple reports coming from Russia. "After the passengers left the aircraft, unexpectedly policemen insistently demanded the crew to leave the plane in order to conduct an inspection there in the absence of the crew," a source told Russian news agency Interfax. Scotland Yard has denied its officers are carrying out a search of the plane. 

 A spokeswoman told Daily Star Online: "I've spoken to our control room at London Heathrow and have confirmed that it is not our force."

In a statement on Twitter, the Met Police posted: "We are aware of a story circulating on social media. Please be advised that Metropolitan Police are not conducting a search of an Airbus inbound from Moscow at Heathrow." But an Aeroflot source has confirmed a plane is being searched at Heathrow, Tom Parfitt, Moscow correspondent for The Times, tweeted. Representatives from the Russian Embassy are reportedly being sent to the scene. Parfitt wrote: "Aeroflot confirms it has plane being inspected at Heathrow. Russian embassy in London says it is sending representatives to the scene. Russian foreign ministry says it is 'inadmissible, dangerous irresponsible' and cd be 'provocation' by UK to save reputation over Skripal affair."

British police "did not explain the reasons" why they were searching the plane and the crew, the source told Interfax. They insisted on inspecting the "entire crew", the source added. Piers Scholfield, foreign news producer for the BBC, tweeted: "FCO has said 'customs officers boarded a plane in London'." BBC journalist Ben Tavener added: "UK Russia plane search: UK Foreign Office confirms to the BBC that it was Customs inspecting the Aeroflot flight at Heathrow this afternoon. The airline says it is willing to cooperate with UK authorities if explanation given." But a spokesperson for the Foreign Office referred Daily Star Online to the Home Office and said "we don't have any information on that". Daily Star Online has contacted the Home Office for comment. Moscow has reportedly called the incident "another provocation" amid simmering tensions over the nerve agent attack on a former Russian spy.

Maria Zakharova, a spokeswoman for the Russian Foreign Ministry, said: “The British authorities asked the Russian crew, including the captain, to leave the plane. "The commander of the aircraft proposed the inspection to be conducted in his presence as he’s forbidden from leaving the plane in accordance with the regulations. "At the moment, the police proceed with the search without releasing the commander from the cabin and preventing him from being present during the inspection." The extraordinary incident comes after ex-KGB agent Sergei Skripal and his daughter Yulia exposed to lethal chemicals in Salisbury on March 4. Russia expled 59 diplomats from 23 countries on Friday as the standoff with the West over the Novichok attack worsens.

The Kremlin rejects Britain's accusation it was behind the attack, with Russian President Vladimir Putin personally branding the allegations "nonsense" and "drivel". In a statement, the NHS said Yulia Skripal, 33, is getting better after spending three weeks in a critical condition due to the nerve toxin attack. Her father, who handed Russian secrets to M16 and moved to the UK on a spy swap, remains in a critical but stable condition. The BBC, citing sources, reported on Friday that Yulia was "conscious and talking".</s>The Russian embassy has accused British authorities of “another blatant provocation” after an Aeroflot flight was allegedly searched by Border Force officers at Heathrow.

Russian Foreign Ministry spokeswoman Maria Zakharova told CNN on Saturday that the number was calculated to ensure the two nations achieve parity in how many staff members they have working at their diplomatic missions.

Russia is now insisting that more leave so the staff will be the same size in the countries' respective embassies.

Also Saturday, Russia's Ministry of Transport said it planned to ask the UK why authorities searched a Moscow-bound Aeroflot plane Friday at London's Heathrow Airport.

On its website, the ministry said, "In the absence of an explanation, the Russian side will regard these actions against our aircraft as illegal, and also reserves the possibility of similar actions against British air carriers."

The UK Security Minister said the search was "routine."

"It is routine for Border Force to search aircraft to protect the UK from (organized) crime and from those who attempt to bring harmful substances like drugs or firearms into the country," spokesman Ben Wallace said in a statement to CNN. "Once these checks were carried out the plane was allowed to carry on with its onward journey."

"We are considering requests for consular access in line with our obligations under international and domestic law, including the rights and wishes of Yulia Skripal," a spokeswoman for the UK's Foreign and Commonwealth Office said Saturday.

On Friday, the Russian Embassy in London tweeted, "Good news as Yulia Skripal is reported as recovering well. We insist on the right to see her, in accordance with the 1968 Consular Convention."
The government of Russia claims that United Kingdom police searched an Aeroflot Airbus jet at Heathrow Airport arriving from Moscow. The Metropolitan Police deny searching the aircraft.
