Margaret Thatcher protests: Teachers of hatred: The drama mistress and the masted from Miliband's school who helped organise the Maggie 'death parties' Special needs teacher Craig Parr, 27, works at Miliband's old school Organised Brixton 'death party', holding 'Rejoice. Thatcher is dead' placard Romany Blythe, 45, created 'The Witch Is Dead Party' Facebook group By Arthur Martin, Ryan Kisiel and Emine Sinmaz Two teachers are today unmasked as key architects of the vile Thatcher "death parties." One is employed at Labour leader Ed Miliband's old school and has worked with the youngest and most impressionable pupils there, while the other teaches troubled and vulnerable children. Yet both were behind disgraceful "celebrations" to mark the passing of Baroness Thatcher. Sick: Special needs teacher Craig Parr, employed at 'Labour's Eton' in north London, is celebrating the death of Margaret Thatcher in Brixton Craig Parr, a teacher at Haverstock School in north London - nicknamed "Labour's Eton" - was pictured parading with a sick placard which read: "Rejoice. Thatcher is dead. The 27-year-old special needs teacher and union activist led chants of "Maggie, Maggie, Maggie, dead, dead, dead" at a death party he organised in Brixton, south London, on Monday night which ended in violent scenes. Meanwhile, drama teacher Romany Blythe, 45, used the internet to encourage thousands to take part in the tasteless celebrations. Miss Blythe, who specialises in teaching troubledchildren at schools in Brighton, wrote of Lady Thatcher: "Who wants to p*** on her grave?" She urged more than 5,000 people to attend a death party in central London by creating an internet page called: "The witch is dead." Last night critics condemned the pair's behaviour as "revolting" and "offensive." 'Come and celebrate our liberty': Romany Blythe is believed to be the teacher behind the macabre 'Witch Is Dead Party!' Facebook groups Douglas Carswell, Tory MP for Clacton in Essex, said: "We must not have teachers working in schools with young people at the public's expense who think it's acceptable to behave like this. Such behaviour is wrong. The fresh revelations about those behind the death parties emerged as: ÷ Sir Mark Thatcher said his mother would be "greatly honoured as well as humbled" by the Queen attending her funeral; ÷ Left-wing MPs, including Glenda Jackson, used a Commons debate to launch vicious attacks on Lady Thatcher; ÷ David Cameron led tributes in the house, saying: "She made the political weather, she made history, and - let this be her epitaph - she made our country great again"; ÷ Union leader Bob Crow provoked outrage by saying he hoped Lady Thatcher would "rot in hell"; and ÷ Police stepped up their operation to thwart efforts by anarchist groups to disrupt the funeral. Mr Parr, a member of the Socialist Workers Party, joined Haverstock School in September last year and was given the sensitive role of teaching children with special needs. He was also made a form teacher for Year 7 children, who at the ages of 11 and 12 are the youngest and most impressionable pupils. Mr Parr is a member of the Lambeth branch of the National Union of Teachers and has previously urged fellow teachers to strike. Last night headteacher John Dowd said he condemned Mr Parr's behaviour "in the strongest possible terms." Mr Dowd said Mr Parr had resigned from his post in February after concerns were raised about his conduct. However, he is still employed by the school and will officially remain a teacher at Haverstock until the end of this month. The school, situated in the fashionable London district of Camden, has been described as a finishing school for the Labour politicians of the future. Hatred: The 45-year-old drama teacher who works with troubled children wrote 'Who wants to p*** on her grave?' Its former pupils include Ed Miliband's brother David, former Labour MP Oona King, Tom Bentley, who is a special adviser to Australia's Labour prime minister Julia Gillard, and the author Zoe Heller. Mr Parr, who was brought up in a modest home in Oxford, will have little or no memory of Lady Thatcher's time in power given that he was just five when she left office. The teacher was invited to speak at a House of Commons committee two months ago on the issues within schools surrounding same-sex marriage. Mr Parr, a member of Schools OUT, an association for gay and lesbian teachers, said pupils should be given a "balanced view" of the world. Wearing a suit and tie, he told MPs that his own beliefs "take a back foot" when teaching. He said: "We have a duty to treat pupils with dignity and build up relationships of mutual respect, and we must also show tolerance and British values." Such noble words appeared to be forgotten in the hours after Lady Thatcher's death on Monday. Dressed in black, he was reported as saying: "We're here to rejoice the death of Thatcher, but her legacy lives on today. We can see that here in Brixton the poorest are suffering with the bedroom tax and benefit caps. If Thatcher was a good Christian woman then maybe she'll go to heaven, but I'm an atheist so I won't worry about that. A snapshot of his Facebook page also provides a disturbing insight. A message written in large letters, which any of his students could find, reads: "We don't need sex, the Government f**** us!" Mr Parr describes himself as a "revolutionary socialist" and appears to support various anarchist groups who have caused unrest in the past. When asked about his actions at his two-bedroom flat in a semi-detached Victorian house in West Norwood, south London, he said: "Why does it matter if I'm a teacher?" Last night Mr Dowd said: "Craig Parr was employed from September 2012 as a teacher of Special Educational Needs on a one-year fixed term contract. He resigned his post in February 2013 due to concerns that I raised with him about his conduct and he has not attended school since that time. His views and actions are his alone, but I would condemn this action in the strongest possible terms. Our approach to the teaching of politics and indeed to developing an objective understanding of the range of political positions, doctrines and views are fundamental to our ethos. Margaret Thatcher's death has clearly led to a polarisation of views about her role as prime minister. As a school community we would offer her our respect and offer our condolences to her family as we would for any of our families suffering bereavement. Meanwhile Mr Parr's fellow rabble-rouser Miss Blythe, 45, stoked up anger by creating a Facebook page called "The witch is dead." On it she called for "demonstrations of disapproval" across the country. She wrote: "So the old bag has copped it finally! Party in the square tomorrow then! Come and celebrate our liberty and freedom from tyranny! On the day Maggie stands down, once and for all! A number of places on the list were the locations of the sick "death parties," including Bristol, London and Glasgow. Miss Blythe is a drama teacher with a workshop company that visits secondary schools. She specialises in "facilitating workshops for young, excluded and potentially criminalised individuals and uses drama techniques she has developed to explore resolution of conflict and oppression," according to the company's website. On Facebook she appears in photographs holding a hammer and sickle flag and posing alongside the former Cabinet Minister Tony Benn. Miss Blythe, of Worthing in West Sussex, could not be reached for comment yesterday. However, in an interview last year, she said her dislike of the former prime minister came from being told she might never find work on leaving school in 1984. With Ed and David Miliband among its alumni, Haverstock School has been nicknamed "Labour's Eton." Labour peer Oona King is also a former pupil of the north London comprehensive, mischievously described as a finishing school for Left-wing politicians. Other old boys and girls include Tom Bentley, a special adviser to Australia's Labour prime minister Julia Gillard and a former adviser to David Blunkett, and the author Zoe Heller, who described her mother as a Labour activist with "Stalinist inclinations." Alumni: Both Labour leader Ed and his brother David Miliband attended the north London comprehensive school Last year Labour leader Ed Miliband - whose father Ralph was a noted Marxist academic - recalled it as being a "really tough school" in his speech to the Labour Party Annual Conference. A Labour Party political broadcast also focused on his education at Haverstock as it aimed to show him as no-nonsense member of the working class. As some observers have pointed out, however, its catchment area included the middle-class Hampstead intelligentsia. In attendance: N-Dubz singer and X Factor judge Tulisa also went to Haverstock In an interview with Piers Morgan, Mr Miliband said he had been beaten up at the school on at least one occasion. But it was subsequently claimed that the fight happened only after he called a fellow pupil a "Turkish b*****d." His brother, former Foreign Secretary David, went back to Haverstock, which became a business and enterprise specialist college under Labour, to give A-level pupils lessons in Government And Politics in 2011. When he asked his class why they wanted to study politics some, who had been on demonstrations, said they did not like the cuts, while others had seen the General Election and wanted to know more, he wrote in an article for the Mail on Sunday. He also took them to visit the House of Commons where there was "a chance meeting" with Dennis Skinner, the outspoken Labour MP for Bolsover and former miner. I asked him to give the students a sense of the history. They were given a lesson in fighting for your rights, fighting for progress - and abolishing the House of Lords. They said they felt they had met a legend," Mr Miliband wrote. Since the the Milibands were pupils, the 1,250-pupil secondary school in Camden has had a major rebuild. David, then Cabinet Minister for the Office of the Deputy Prime Minister, was among the guests at the opening of the £21million project in 2006. Other well-known former Haverstock pupils include the footballers John Barnes and Joe Cole, and X Factor judge Tulisa Contostavlos.
