The final poll to be released ahead of votes closing in the EU referendum shows Remain ahead – but only just.

The Ipsos Mori survey for the Evening Standard showed the In camp ahead of leave by 52 per cent to 48 per cent.

But 12 per cent of those polled said that they would still be ready to switch sides, adding uncertainty to the results.

Further complications may be added by terrible weather – particularly rain storms in the Remain stronghold of London. Some fear that the bad weather could lead people not to cast their ballots and so reduce turnout, which would help the Leave campaign.

Though the Ipsos Mori poll is the final one to be published, it isn’t the latest one to be conducted. Polling for the recently-released Populus poll finished at midnight the day before voting opened – and showed a far wider lead for Remain.

Ukip leader Nigel Farage insisted his side could pull off an historic victory if "soft" In voters stayed home.

"Actually I do think we are in with a very strong chance, I do genuinely. But it's all about turnout and those soft Remainers staying at home. I do think that the people who have decided to vote Leave have a real conviction and passion," Mr Farage said.

However, early indications showed long queues snaking outside voting centres as the nation braved the storms to decide Britain's future role in Europe.

But some polling stations were forced to close, and many others are flooded due to the heavy rain sweeping the capital.

Kingston upon Thames Council in south west London moved two polling stations after they became inundated with water.

Prime Minister David Cameron ignored questions about the weather, saying only "Good morning" to the gathered media from across the world, as he and wife Samantha cast their votes at Methodist Hall in Westminster.

Labour leader Jeremy Corbyn arrived in a positive mood to cast his vote in his Islington constituency in north London.

Asked if he was feeing confident, Mr Corbyn smiled and said: "Extremely, it's a very good day."

On the outcome of the referendum, he joked: "You could either check the wind or check the bookies," adding "the bookies usually get it right".

Pro-Leave Justice Secretary Michael Gove said he was feeling "quite excited" as he accompanied his wife, Sarah Vine, to a polling station in North Kensington.

The referendum has seen one of the longest, and most personally bitter, campaigns in recent British political memory.

Both sides of the campaign have been locked in fierce fighting for months, and things came to a frenetic close on Wednesday as senior politicians criss-crossed across the country to try to sway undecided voters.

The Prime Minister and his Remain colleagues from across the political spectrum have warned of the potentially severe economic consequences of a Brexit vote amid fears of financial market turmoil and another recession.

But Leave campaigners, led by Tory heavyweight Boris Johnson, have urged voters to "take back control" of the country.

Mr Farage would not elaborate on his reasons for missing Wednesday night's final Channel 4 debate of the campaign, saying only that it was "for family reasons".

He came in for particularly stern criticism after unveiling a Brexit poster showing a queue of hundreds of immigrants arriving in Europe with the slogan "breaking point".

And Leave campaigners were left furious after Chancellor George Osborne made use of Treasury research to warn that quitting the EU would result in households being £4,300 a year worse off.

Meanwhile, dozens of celebrities have intervened during the course of the campaign to make their feelings known.

Footballer David Beckham, James Bond actor Daniel Craig and Harry Potter author JK Rowling were just three of the high-profile names to back the Remain campaign, while Leave won support from the likes of comedian John Cleese, former cricketer Sir Ian Botham and former England football player Sol Campbell.

A record number of voters are eligible to take part in the referendum, with the Electoral Commission putting the number at 46,499,537.

Polling stations will close at 10pm.

Fieldwork for Ipsos Mori's survey of 1,592 people was carried out until 9pm on Wednesday night.
