Sally Bercow has admitted she is “a terrible wife” after she was accused of having an affair with her husband John Bercow’s cousin, adding she had been "left heartbroken" by her alleged lover.
Mrs Bercow did not deny cheating on her husband, the Speaker of the Commons, with Alan Bercow as she left her home without her wedding ring.
She said she had hated the six "lonely" years living with John Bercow in Parliament, and vowed: “I won't go back.”
Mrs Bercow has previously taken part in Celebrity Big Brother, reality show The Jump and and had a Channel 5 series with Paddy Doherty.
Her affair is said to have begun at the start of the general election campaign, when the Speaker campaigned in his Buckingham constituency and his cousin moved into a £1.2 million mews house in Battersea jointly owned by John and Sally Bercow.
Alan Bercow’s wife Erica has confirmed that the affair happened, but the 57-year-old solicitor has now moved back into his marital home with his wife and ten-year-old son after the relationship with Sally Bercow ended a week ago.
Yesterday Mrs Bercow was at the Battersea house alone, while the Speaker was at his grace and favour flat in Parliament with their three children.
Appearing without her wedding ring on she admitted she has had "a difficult marriage for a long time, primarily because we're living in Parliament and I hate it there."
She said her husband John was "not a weak man" who was "very forgiving" however she added: "But I'm not sure I want to be forgiven."
She "wouldn't at all blame him if he thinks 'right I've had enough, she's embarrassed me enough.' He's a good man and he's sucked it up enough in some respects."
In a double blow to her Speaker husband, there was also speculation he could face a fight to keep his job, with rumours that Conservatives might use their majority to make a second attempt to oust him.
Speaking outside her riverside house in Battersea, she appeared angry and resigned as she initially said she did not want to talk about the affair.
But of her husband she said: "I'm saying he's a great dad and a great speaker.
"Am I a good wife? I'm a terrible wife. I'm a terrible wife. I always have been. If I was John I wouldn't put up with me. I'm not even going to say that he'll take me back.
"I'm not even confirming that I've had an affair with the cousin.
"I'm not even talking about it. I'm not even talking about personal matters, not even going to talk about it. I don't think it's relevant.
"It's up to John, he's the public figure I'm not. No marriage is perfect, no marriage is perfect, if John wants me back he's crazy.
"If I was John, I wouldn't put up with it. But I'm a strong woman, I wouldn't put up with it.
"He's not a weak man, he's an amazing man. He loves me very much. Is he a forgiving man? Very. But I'm not sure I want to be forgiven.
"Alan's left me f*****g heartbroken."
She said she loved living in Battersea away from Parliament and added: "I've asked John for the last six years if we can leave. I hate it, I hate living in Parliament, it's like living in a goldfish bowl.
"Since living here the last few weeks I've loved it. I've loved it. I like picking up my kids from school without going back through security.
"Having my friend knocking on my door without having to go through security. I hate parliament I always have done. It's a time warp, it's full of flunkies"
"If John wanted to move down here with me fabulous.
"I'm not even talking about the cousin, I'm not. It's not lonely here. It was lonely in Parliament.
"This is normal life. I've got three kids they can play football out here. It wasn't our furniture. All these portraits of f****** politicians from the 18 century.
"Alan Bercow was a great friend of mine and remains a great friend of mine.
"John and I have had a difficult marriage for a long time, primarily because we're living in Parliament and I hate it there.
"My husband is a good man. I can't tell you how awful it is living in parliament. I just don't want to go back.
"If he wants to come here than great. But I wouldn't at all blame him if he thinks 'right I've had enough, she's embarrassed me enough.'
"I wouldn't at all blame him. He's a good man and he's sucked it up enough in some respects."
Dressed in canvas shoes, skinny jeans, a blue top with large polka dots and sunglasses, Mrs Bercow, 45, posed on crutches on the Thames path outside her house. She is still recovering after breaking her leg in nine places while on a family skiing holiday.
The rumours that Mr Bercow might also face a fight to keep his role as Speaker because of his unpopularity with senior Tories were dismissed by Conservative Party sources who said there was no plot to oust him.
An attempt to depose the 52-year-old Speaker six weeks ago was a failure, and with the Conservatives winning a narrow majority in last week’s election they are wary of alienating Mr Bercow’s friends in the party.
It is not the first time Mrs Bercow, who was a contestant in Celebrity Big Brother in 2011, has been accused of involvement with other men. She was photographed last year kissing DJ Clinton Baugh at a West End club.
Mrs Bercow, wearing a brown wig, was reported to have spent several minutes canoodling with Mr Baugh.
According to the Mail on Sunday she became close to Alan Bercow through a mutual appreciation of fine wine, a subject about which he “decided to instruct her”.
When the newspaper asked Erica Bercow if her husband had been unfaithful, she said: “Yes, but I can’t make any comment. We have our child here, someone has to be dignified. We are very much together and that’s all I want to say.”
When Alan Bercow was asked if he had been in a sexual relationship with Sally Bercow, he said: “I don’t have any comment.”
Sally Bercow, a Labour supporter, said of the election result: “I am devastated David Cameron got in. I can talk about the election until the cows come home. I think John will keep hold of the speakership. He’s a brilliant Speaker, I mean he’s a fabulous man. He’s a brilliant dad.
“Parliament needs him to be honest. I think Dave is going to have to be very careful with his small majority.
“They tried that stupid coup against him just before the election and that failed. I think they would be foolish to make it their top priority.
“He’s a great Speaker, he stands up for backbenchers. He’s a great man and a good dad.”
John Bercow was unavailable for comment.
