Ed Davey became leader of the Liberal Democrats almost five months ago. Since then, his party has achieved nothing. The Lib Dems currently poll at around five per cent, meaning that a party that only six years ago was in government now enjoys less support than the Greens. If this is embarrassing, it isn’t surprising: the Lib Dems have had little to say for a very long time and certainly not since Davey took the reins.
