UKIP's Nigel Farage has clashed with former Tory leader Iain Duncan Smith over a referendum to leave the European Union.

Mr Farage said David Cameron had given a "cast iron guarantee" of a vote on the EU at the last election but on Monday with other party leaders prevented the Commons voting for one in the debate sparked by an e-petition from the public.

Mr Duncan Smith accused Mr Farage of talking rubbish and playing games.
