Poll blow for Nick Clegg as voters prefer Vince Cable as leader The ICM survey for The Sunday Telegraph puts Mr Cable, who has not ruled himself out as a future leader, 11 points ahead of Mr Clegg among voters of all parties. Among Lib Dem supporters, Mr Cable's lead is seven per cent. However, it is not good news for Mr Clegg personally, who last week made a televised apology for making a pledge not to increase university tuition fees before the last election and then breaking it in government. When asked whose leadership would attract most voters to the party, 21 per cent of all those polled picked Mr Clegg, with 32 per cent identifying Mr Cable, the Business Secretary. Among Lib Dem supporters, Mr Cable was chosen by 30 per cent with Mr Clegg on 23 per cent. Mr Cable said two months ago that he "would not exclude" leading the Lib Dems in the future, adding "who knows what might happen" He did not stand in the 2007 contest to succeed Sir Menzies Campbell as the party's leader. ICM Research interviewed a sample of 2,029 adults aged 18+ online on 20-21st September 2012. The results have been weighted to the profile of all adults.
