Cameron to co-operate with India over deal British PM David Cameron David Cameron has arrived in India for a three day visit. BRITISH Prime Minister David Cameron promised full co-operation with India and its police as a probe into alleged kickbacks in a helicopter deal clouded his meetings with leaders in New Delhi. Cameron arrived in India on Monday with what he called the biggest-ever British overseas business delegation, pushing for better access to the booming market of 1.2 billion people and greater trade. While keen to still convince India of the merits of the part-British Eurofighter military jets, he has been dogged by another defence deal involving the Anglo-Italian helicopter maker AgustaWestland. Italian authorities made arrests last week during an investigation into bribes allegedly paid to secure the $US750 million ($A732.03 million) contract in 2010, and leaks to the press indicate one of the accused middlemen is based in London. The helicopters are being made in southwest Britain. I haven't received an approach (from the Indian government about the case). Any approach we do get we will obviously co-operate with in full," Cameron told Indian channel NDTV. These are allegations that have been made and the Indian authorities and the Italian authorities will want to get to the truth. If there are unacceptable practices then that needs to be dealt with. The first allegations of wrong-doing emerged last year, but India's government has said it was unable to gain information from Italian or British governments about their investigation. Just a year ahead of national polls, the new scandal has rocked the government of Manmohan Singh and his Defence Minister A.K. Antony who ordered a police probe last week and has started the process of cancelling the deal. Cameron sits down with Manmohan Singh for talks on Tuesday before meetings with President Pranab Mukherjee and the head of the ruling Congress party Sonia Gandhi. Cameron and Singh are set to announce a "substantial" strengthening of co-operation in cyber-security, an area of mutual concern as many British companies store data in India, reports say.
