Sign up to TV debates or we’ll go ahead without you, leaders warn Cameron
Labour, the Lib Dems and Ukip are having quite a bit of fun with their identical letters from their respective leaders demanding that David Cameron take part in the TV debates - or risk having something done to him that is even worse than a noun being turned into a verb (the latest threat is that he will be ‘empty-podiumed’, which sounds considerably more unpleasant than being ‘empty-chaired’ and possibly as bad as someone ‘weaponising’ something).
