Rival Brexit camps battle into eve of referendum

Rival sides threw their efforts into the final day of campaigning on Wednesday, on the eve of Britain's vote on EU membership that will shape the future of Europe.

Prime Minister David Cameron conducted a spate of last-minute interviews to get his pro-EU message to voters before polls open at 06:00 GMT on Thursday.

The "Remain" camp has the slimmest possible lead on 51% versus 49% support for the "Leave" side, according to an average of polls compiled by What UK Thinks.

In a final push to win over the undecided voters who could tip the referendum, campaigners will speak at rival "Leave" and "Remain" rallies taking place within hours of each other in London.
