Sally Bercow, the wife of the House of Commons Speaker, said she has "nothing to be ashamed of" after The Sun published pictures of her apparently kissing another man on a night out.
“The guy in the picture is a friend. End of," she told the Evening Standard. "I can’t wait until John finishes being Speaker, maybe then the media will leave me alone.
“My marriage is my business," she said. "I couldn’t give a damn what people think. Let people judge me if they want."
The 44-year-old described her husband as the "most important man in my life" and said the pictures were taken on Saturday at a friend’s birthday party.
"Yes, I go out and have fun, but I have done nothing to be ashamed of," she added.
Lord McAlpine's libel action against the House of Commons Speaker's wife Sally Bercow has been formally settled at the High Court.
Lord McAlpine's QC, Sir Edward Garnier, told the judge that Mrs Bercow had apologised for her "irresponsible use of Twitter" following a report that falsely implicated the Conservative peer in abuse allegations.
She accepted an offer to settle the matter in May after Mr Justice Tugendhat ruled that the tweet in question was highly defamatory.
Mrs Bercow's QC, William McCormick, said today: "Mrs Bercow wishes and hopes that as a result of this matter other Twitter users will behave more responsibly in how they use that platform. She certainly intends to do so herself."
He added that should Mrs Bercow reactivate her Twitter account, it is now a legal requirement that she must formally issue her apology on it.
Lord McAlpine's lawyer said Sally Bercow "must now accept" that her tweet about the Conservative peer was defamatory after the High Court ruled it was libellous.
Andrew Reid of RMPI Solicitors said:
The High Court judge who ruled a tweet by Sally Bercow about Lord McAlpine was libellous said her followers - who numbered 56,000 - would likely know by the time of her post the elements of the story told on Newsnight.
"In my judgement, the reasonable reader would understand the words 'innocent face' as being insincere and ironical", Mr Justice Tugendhat said.
"There is no sensible reason for including those words in the tweet if they are to be taken as meaning that the defendant simply wants to know the answer to a factual question".
The reader would reasonably infer that Mrs Bercow had provided "the last piece in the jigsaw".
Her tweet, by implication, was a repetition of the accusation with the addition of the name which had previously been omitted.
"It is an allegation of guilt. I see no room on these facts for any less serious meaning", the judge said.
Sally Bercow said the High Court's ruling that her tweet about Lord McAlpine was libellous "should be seen as a warning to all social media users".
Mrs Bercow said in a statement that she did not write the tweet "with malice" and "did not intend to libel" the Conservative peer.
Sally Bercow said she has "accepted an earlier offer" made by Lord McAlpine's lawyers "to settle this matter" after the High Court ruled a tweet she wrote about the Conservative peer was libellous.
Sally Bercow said she was "surprised and disappointed" after the High Court ruled a tweet she wrote about Lord McAlpine was libellous.
Mrs Bercow added, "However, I will accept the ruling as the end of the matter. I remain sorry for the distress I have caused Lord McAlpine and I repeat my apologies".
A tweet by Commons Speaker's wife Sally Bercow about Lord McAlpine was libellous the High Court in London ruled today.
