EU Referendum: David Cameron 'battling for Britain' at EU talks
David Cameron said he was "battling for Britain" as he arrived in Brussels for a crucial EU summit.
European Commission President Jean-Claude Juncker has said he is "quite confident" European leaders can reach a deal with Britain over its future membership of the EU.
Mr Cameron aims to return with a reform package he can put to the British people in a referendum in June.
