Westminster's sleaze watchdog was yesterday considering launching an inquiry into the conduct of Labour MP Nigel Griffiths, who reportedly cheated on his wife in the Commons.
The office of Standards Commissioner John Lyon confirmed he had received emails of complaint over the Edinburgh South MP’s conduct.
Mr Griffiths has expressed “shame” over the reports in the News of the World at the weekend, and said his behaviour fell “below acceptable standards”.
A spokeswoman for Mr Lyon said: “He has received complaints by email, and we are looking at them.”
The News of the World said Mr Griffiths had a tryst with another woman in his office at the House of Commons on Remembrance Day last year.
Mr Griffiths, who has been married to wife Sally for 30 years, said: “I am, of course, ashamed that my conduct did fall below acceptable standards. I have little recollection of the evening, but that does not make it right.”
