Whistle-blowing MP had an affair of his own
John Hemming: used parliamentary privilege
British MP John Hemming has helped unveil attempts to cover up the alleged affairs of ex-banker Fred Goodwin and, now, Manchester United star Ryan Giggs.
But the Liberal Democrat backbencher himself had to own up to extra-marital sexual relations soon after becoming an MP in 2005.
The 51-year-old millionaire Oxford graduate fathered a child with personal assistant Emily Cox during a long-standing affair. He got married in 1982, having one son and two daughters with wife Christine, who is currently awaiting trial over the theft of Ms Cox's kitten last year.
Mr Hemming has regularly made recourse to the rights of parliament before yesterday's naming of Giggs as the Premier League footballer at the centre of the Twitter row.
Last year, a leading law firm was found "in contempt" of parliament for threatening the MP with legal proceedings if he made allegations about one of its clients.
In March this year, Mr Hemming used parliamentary privilege to speak out about the use of injunctions, censorship and creeping privacy laws.
He announced the existence of an injunction that banned a man from talking about court proceedings in which he was involved, including to his MP.
Mr Hemming also revealed that former Royal Bank of Scotland chief Fred Goodwin had obtained an injunction. The court gagging order was so strict it even banned referring to Mr Goodwin as "a banker".
Lib Dem peer Lord Stoneham told the Lords last week that the injunction related to a sexual relationship with a senior colleague.
