text: George Osborne today brushed off Labour's class war attacks, mocking Harriet Harman on live television over the fact they both went to the same private school. Challenged about claims senior Tories are 'posh boys', Ms Harman, Labour's deputy leader, insisted they were only 'standing up for people at the top'. But sharing a breakfast TV sofa with her was Mr Osborne, who said that as they both went to St Paul's School in London, 'the posh boy attack always sounds a bit thin'. Scroll down for video . Labour's deputy leader Harriet Harman and Tory Chancellor George Osborne, who both went to the same school, shared a sofa on the TV this morning . In the 1980s, Mr Osborne attended St Paul's School for boys, where a place for a pupil boarding costs now £10,800-a-year. Ms Harman went to St Paul's Girls School in the 1960s . In the 1980s, Mr Osborne attended St Paul's School for boys, where a place for a pupil boarding costs £10,800-a-year. Ms Harman, who went to St Paul's Girls School in the 1960s, has repeatedly accused the Tories of being 'completely out of touch'. She has previously faced the wrath of Labour backbenchers when she sent her son and daughter to selective grammar schools. Appearing on BBC One's Andrew Marr show, Ms Harman complained about Tory attacks on Ed Miliband that he 'stabbed his brother in the back' for the Labour leadership. Host Andrew Marr asked: 'Is that somehow worse than accusing George Osborne and David Cameron of being 'posh boys'? Is there any difference really?' Challenged about claims senior Tories are 'posh boys', Ms Harman, Labour's deputy leader, insisted they were only 'standing up for people at the top'. Ms Harman did not resile from the class-based attacks, and added: 'Well I think we're saying they're standing up for people at the top and everybody else has been suffering and the recovery hasn't reached people. 'But that is quite different from saying that as Prime Minister Ed Miliband would stab this country in the back.' But sitting barely three feet away on the couch, Mr Osborne shot back: 'Well Harriet and I went to the same school, so the posh boy attack always sounds a bit thin when coming from her. 'But the point I'd make is we've got a really positive vision for this country and actually I've found this campaign enormously energising and exciting. 'And I go round the country - people are switched on, people do care about this country's future.' Ms Harman attacked the Tories over their commitment to spend an extra £8billion on the NHS, insisting it was 'absolutely illusory' Earlier Ms Harman said Conservative plans for 'extreme' spending cuts would inevitably mean further cutbacks to health. 'The reality is that the spending programme that they have put forward is a threat to cut the NHS. It is absolutely illusory. 'I don't think that people will believe it anyway. People know that they find it harder to see their GP since the Tories came into government, they know that they wait longer in accident and emergency and that waiting lists are starting to grow.' Mr Osborne insisted, however, that the Conservatives had shown in government that they were able to make the savings necessary to deliver additional funding for the NHS. 'We have a balanced plan to grow our economy, to make savings in government including in welfare to fund our NHS each and every year,' he said. 'We have to make similar savings each year that we have made for five years of this parliament but for two years. 'We have a track record in this parliament where we found almost £8 billion extra in real terms for the National Health Service in very, very difficult economic circumstances so we have proved our mettle, we have proved our ability to stand behind the National Health Service in this parliament. We can do it in the next.'
