Liberal Democrats leader, Sir Vince Cable, has told Sheffield Live! his party’s promise not to increase tuition fees during the campaign in the 2010 general election “was a bad mistake”. The former Business Secretary was in Sheffield to meet with Lib Dem activists to discuss party policies and to support the campaign to save from closure the NHS Walk-in Centre on Broad Lane and the Minor Injuries Unit at Hallamshire Hospital.
