MP Peter Hain outraged files kept on him by Scotland Yard

Welsh MP Peter Hain said he is "deeply disturbed" after a former undercover police officer told BBC News that Scotland Yard kept intelligence files on MPs during the 1990s.

The former Special Branch officer, Peter Francis, says he saw 10 files which he and others regularly updated.

He says he personally gathered information on three MPs as part of his work infiltrating left-wing groups.

MPs named by Mr Francis have called for a forthcoming public inquiry into undercover policing to be widened.

Between 1990 and 2001, he claims to have personally seen records relating to Diane Abbott, the late Tony Benn, Jeremy Corbyn, the late Bernie Grant, outgoing Neath MP Peter Hain, Harriet Harman, Ken Livingstone, Joan Ruddock, Dennis Skinner and Jack Straw.
