Final Push As Polls Show EU Vote On Knife-Edge

The Prime Minister has ended his final day of campaigning in the EU referendum by declaring "we are stronger" in a reformed European Union, while Boris Johnson has said Brexit would allow Britain to "flourish as never before".

David Cameron has been travelling across Britain - appearing with the likes of former prime minister Sir John Major and Labour's Harriet Harman - to urge the country vote Remain.

As both Stronger In and Vote Leave wound up their respective campaigns ahead of voting beginning at 7am on Thursday, two opinion polls suggest the result remains on a knife edge.

In his final public speech before voters have their say, the PM said figures from across the political spectrum are united in urging the country to vote to stay in.

He said: "We are all saying the same thing - we are stronger, we are better off, we are safer in a reformed European Union."

Mr Cameron urged Britons to think of the word "together" as they head to the polls, telling an audience in Birmingham: "There is no problem we are facing in our world today, facing our country today, that isn't helped by working together.

"How are we going to get that bigger and stronger economy, are we going to do it on our own? No, we are going to do it together with others."

On the Leave side, campaigner Boris Johnson has seized on comments by European Commission President Jean-Claude Juncker about the referendum to press his case for the public to opt for Brexit.

Mr Juncker has warned "out is out" if British voters decide to leave.

He also said Mr Cameron had secured the "maximum" Brussels could give, adding there will be no further renegotiations on Britain's EU relationship.

Mr Johnson condemned Mr Juncker as an "unelected tinpot figure", and added: "Who elected Jean-Claude Juncker to run anything in this way? Who put him in charge of us in this way?

"This gives the game away. If we stay in there is no prospect of any further change.

"This is it, folks. We have been told from the horse's mouth that any hope of further change is absolute illusion."

The final stop on Mr Johnson's last day of campaigning was The George pub at Piercebridge, County Durham, where he pulled a pint and delivered a rallying cry from behind the bar.

He told supporters to "drive for the line" and took the opportunity to hit out at Mr Juncker once more, saying his remarks "tell you all you need to know about the conceit of EU officials".

He added: "The idea that we can do better by staying in the EU is a sham, a snare and a delusion."

Brexit would allow "our democracy to flourish as never before", Mr Johnson predicted.

He has insisted he has "no regrets" over backing Brexit, and dismissed predictions such an outcome would lead to panic on the stock markets on Friday.

Meanwhile, Labour leader Jeremy Corbyn has been doing his best to push the case for Remain, telling a rally in London: "We believe to remain will be able to help us reform the European Union and would be right for people in this country.

"We can make this country and the world a better place if we work with other people."

UKIP leader Nigel Farage opted to appeal to voters' patriotism as he urged a vote to leave.

He said: "At the end of the day tomorrow when people vote they have to make a decision - which flag is theirs? I want us to live under British passports and under the British flag."

Earlier, prominent Vote Leave campaigner Michael Gove was forced to apologise after comparing economists who have warned of the dangers of Brexit to scientists in the pay of the Nazis who smeared Albert Einstein in the 1930s.
