There's just a day to go before Britain goes to the polls to decide whether or not to leave the EU, and tensions are reaching a climax.

Among the latest supporters for remaining in the EU are legendary investor George Soros and former English football captain David Beckham.

However, as CCTV's Richard Bestic reports from London, opinion polls still give no clue about the outcome.

With campaigning in the final stretch, opinion polls are running neck and neck, giving no clues as how the result may go.In Britain, a rally of young people are more inclined it's believed to vote to remain in the European Union.

Prime Minister David Cameron was on the steps of his official residence at 10 Downing Street, appealing to older voters and warning of the economic risks of leaving.

"We'll be stronger, we'll be safer and better off inside Europe. To put it as clearly as I can, our economic security is paramount. It is stronger if we stay, if we leave we put it at risk. That is a risk to jobs; a risk to families a risk to our children's future. And there is no going back," he said. 

"Vote for your future in Europe-that's the message they're putting across here and certainly all the economic arguments from bodies around the world, would seem to suggest that Britain would be better off inside the EU," said the reporter.

In the final televised campaign of the referendum, controlling borders and taking back national sovereignty is equally important to some.

Boris Johnson, Member of Parliament maintained, "Reaction among many in the audience of 6,000 was testament, perhaps, to the strength of feeling in Britain over the manner in which the European Union is being run."
