Coalition curse strikes again: Cameron¿s advisor on children becomes the latest Tory MP to split from her husband Devies MP Claire Perry reveals her 17-year marriage to Clayton is over One in six Tory MPs first elected in 2010 have suffered relationship breakdown as pressure of politics becomes too much David Cameron's advisor on childhood has become the latest Tory MP to reveal her marriage is over. Claire Perry announced her 17-year marriage to husband Clayton was over after becoming "increasingly difficult for several years." It comes amid claims one in six new Conservative MPs has divorced, separated or ended long-term relationships since the coalition was formed in 2010. Devizes MP Claire Perry, who was only elected to the Commons in 2010, has revealed her 17-year marriage marriage to husband Clayton, right, is over Mrs Perry, MP for Devizes, has seen her profile rise dramatically since being asked by the Prime Minister to lead policy on childhood. But she hinted that her workload in Westminster had taken its toll. "We both have demanding jobs and for some time we have been leading very separate lives," she told the Wiltshire Gazette and Herald. But we still live under the same roof in Wiltshire and in London and it is entirely manageable. Mr and Mrs Perry have a son and two daughters She insisted the split was amicable. Our marriage has become increasingly difficult for several years. It's nobody's fault, no one is to blame, despite our best efforts, we have just grown steadily apart. The couple met in New York in 1994 when they worked in the financial sector. They married in 1996 and have one son and two daughters. She was elected as MP for Devizes in 2010. She added: "After 19 years together our primary focus is on our children. It is terribly sad and difficult for them and they are and will always be our main priority. The couple have not yet begun a divorce. However, it is thought one in six of newly-elected Tory MPs have seen their relationships break down as the pressures of political life have mounted. In an interview earlier this month, Mrs Perry insisted she did not regret giving up her job in the City to raise her children. 'I loved it unashamedly,' she told The Times. Why would you want to pay a nanny to take them to the park when you could do it yourself? I like babies, I like children, I wanted to be at home and be mummy. Last year David Cameron appointed Mrs Perry has his advisor on childhood and sexualisation of children Despite only being elected three years ago, Mrs Perry has built a high profile in Westminster as an outspoken campaigner on internet porn and raising children She went on: 'The world runs on frustrated women who could be running corporations but are staying at home with their kids. Having said that, losing touch with the workplace was the worst thing I ever did. There's a crisis of confidence when women go back to work.' Last month Tory MP Charles Walker revealed said 23 of the 147 Conservatives elected for the first time in 2010 had been affected. He believes this is equivalent to a sixth of those who were in a relationship at the general election. He in part blamed scrutiny of their private lives and expense claims for piling pressure on the rookie MPs. Novelist Louise Mensch last year quit as MP for Corby to move to New York with her family Mr Walker told the Sunday Times: "They thought it was going to be different [compared with those caught up in the expenses scandal]. Then suddenly they began to appear on the front page of their local newspaper for buying an iPad or a packet of biscuits for the office. Louise Mensch quit the Commons in April last year, citing the pressure on her family. She has since moved to New York to be with her husband. "I deeply regret, and always will, that the extraordinary strain of separation from my spouse and the prospect of that separation becoming permanent demanded my resignation," she said.
