Greg Hands, Conservative MP for Chelsea and Fulham and former Hammersmith and Fulham councillor, blamed “Labour lies” for his party’s defeat.
‘Cameron’s favourite council’
He said Labour’s campaigning had been “entirely dishonest” about the future of Charing Cross Hospital.
He said: “There are a lot of Labour lies about Charing Cross Hospital. The old building was going to be demolished but replaced with a new build hospital and A&E.”
Labour’s Stephen Cowan, the new leader of Hammersmith and Fulham, described Mr Hands’s response to his party’s defeat “as sour grapes” and denied lies had been told.
He added they had “voted Labour in David Cameron’s favourite council”, sending a clear message.
