London, Mar 24 : Brit MP Nigel Griffiths, who had cheated on his wife by romping in the Commons on Remembrance Day, will be facing a probe by Westminster's watchdog.

Emails complaining about the Edinburgh South MP's conduct have been received by Standards Commissioner John Lyon's office, reports The Sun.

Griffiths, 53, who is a pal of Gordon Brown, has admitted his behaviour with a mystery brunette fell "below acceptable standards".

London, March 22 : A British newspaper alleges it has evidence that Senior Labour MP Nigel Griffiths cheated on his wife by having sex with a brunette inside House of Commons.

According to News of the World, the 53-year-old disgraced his marriage and Parliament office after smuggling the woman into his study on Remembrance Day, the day the country honours its war heroes.

Griffiths, who has been married to Sally McLaughlin since 1979, was claimed to have recorded his hour-long midnight sex with the lady on the sofa in the oak-panelled study on November 11 last year.
