Conservative MP Bob Blackman is claimed to have had an 11-year affair with Carol Shaw when they were both councillors . A Tory MP who said that marriage could work only between ‘one man and one woman’ has been accused of hypocrisy – by his alleged former mistress. Bob Blackman, 58, who made the comments in opposition to gay marriage, is claimed to have had an 11-year affair that started just one year after he married his  wife Nicola. His alleged former mistress, Carol Shaw, claims that they  had the long-term affair while they were both Conservative councillors. She said that Mr Blackman is an . ‘absolute hypocrite’ for making the comments about gay marriage last . month considering his infidelity, which she claims included sex in his . marital bed  and at an office. Speaking . about the affair for the first time, Miss Shaw, 62, said: ‘I couldn’t . believe a man who had an affair with me for over 11 years could have the . cheek to preach about the sanctity of marriage. ‘You . have to be squeaky clean to do that and he has made a mistake. Bob is . an absolute hypocrite. He talks about marriage being between one man and . one woman ... but why does he not practice what he preaches. ‘More . than once I asked about his wife and I got the impression one day he . might leave her, because he said he could love two people at the same . time.’ Mr Blackman last . month said that he believed marriage had to be ‘between one man and one . woman’ as he claimed in an interview that David Cameron’s backing of . religious same-sex marriages was wrong on ‘principle’. But . Miss Shaw claims that their affair began just a year after he married . his wife in 1988 when  all three of them were councillors on Brent . Council in North-West London. Miss Shaw said that they first had sex . after Mr Blackman dropped her off at her flat after a function, but it . then became a regular occurrence with frequent Friday afternoon meetings . at her home. ‘Bob was a terrible lover but I was madly in love with him,’ she said in the interview with the Sunday Mirror. ‘He wasn’t one of these . four-times-a-night lovers. He’d never try anything new. He would just . say, “I haven’t got much time”. He just wanted to get into it. Mr Blackman, pictured here with David Cameron, became an MP in 2010 and said marriage could work only between 'one man and one woman' ‘It was once and then he would fall asleep. He would snore and I would have to wake him up.’ Miss Shaw said that the affair ended in 2000 when she became frustrated with the relationship. She . added: ‘Eleven years is a long time to carry on an affair. It’s not . like it was a one-night stand. He must have been desperately  miserable . in his marriage... or  he found me irresistible. I hope it’s the . latter.’ Miss Shaw, who is still a councillor in Brent, defected to the  Liberal Democrats in 2003. Mr Blackman was elected MP for Harrow East in 2010.
