1247 - ALLEGED REGISTRATION ERRORS DISRUPT VOTING
The Express reported that "dozens of voters were turned away when they arrived to [cast] their vote" in a polling station in Bedfordshire:
"Residents in Leighton Buzzard were unable to have their say after they were told they were not included on the registration list.
"Angry residents hit out, describing the situation as a "total shambles" and Central Beds Council eventually made arrangements for voters who had missed out."
Meanwhile, it seems other voters are getting similar rejections in being able to vote, despite having a polling card:

Torrential rain has battered London throughout the day as the public finally goes out to vote on the EU referendum.
And as a result, the Conservative party campaign headquarters flooded.
1202 - THE REFERENDUM IS NOT LEGALLY BINDING - IN THEORY
A really crucial detail about the EU referendum has gone virtually unmentioned and it is probably the most crucial detail: Parliament does not actually have to bring Britain out of the EU if the public votes for it.
That is because the result of the referendum on Britain's EU membership is not legally binding. Instead, it is merely advisory and in theory, could be totally ignored by UK government.
For more on this see Business Insider's intriguing interview with the University of Westminster's Peter Catterall - This is why a Brexit will most likely not actually happen even if the public votes for it.

People are posting pictures and videos on Twitter of flooding. Bad weather is historically bad for voting turnout. After all, if you can't physically get to the polling station, how will you cast your vote?

But in all seriousness, if you mark a "√" in the ballot form box, it will render the ballot "spoiled." Your vote won't count.
Remember, if you intentionally do not want to spoil you ballot form, mark an "X" in the box:

Here's an example:
Of course, BI will bring you a selection of the best snaps later on.
1004 - THIS CHART SHOWS HOW STATUS QUO CAN SWING THE VOTE AT THE LAST MINUTE
Deutsche Bank's Jim Reid said in a note on Thursday, which was sent to Deutsche Bank clients: "As we highlighted last week, there seemed to be either a late swing or error in polling that underestimated the support for the 'remain' movement in the Quebec/Scottish referendums."
This led to a stronger remain vote than had been forecast.
Here's the chart from Deutsche Bank:

0758 - KEY TIMES FOR THIS EVENING AND POLLS
There will be NO EXIT POLLS this evening. This means when voting stops at 10 p.m. BST, unlike the General Election, there will be no official exit polls to gauge how people have voted.
However, banks and hedge funds have paid for their own exit polls. This means, only employees will be privy to the polls, which should give some inclination to how people have voted.
Meanwhile, Sky News has commissioned a survey from YouGov, asking people how they voted on the day. This will be released at 10 p.m. BST. However this is NOT an authoritative exit poll.
HSBC says:
"Unlike in a general election, there will be no authoritative exit polls. Given there is no precedent, it is hard for pollsters to know at which polling stations to conduct exit polls in order to get a good proxy for the wider country."
However, HSBC has pinpointed some key areas to gauge opinion during the count:
