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.
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.
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.
