In the past 24 hours, two former footballers and a German newspaper have pledged allegiance to the Remain camp, while polls suggest the result remains on a knife-edge.
Here are five things we learned about the EU referendum campaign on the final day before the UK goes to the polls.
1. The Tories seem to be the most united party.
Much of the narrative of the EU referendum campaign has focused on divisions within the Conservative Party. But polling by Ipsos Mori shows the Tories are still seen as the most united party in England, with one in four people saying so and just 13% saying Labour. However, the numbers do suggest the referendum campaign is having an effect on the Tories - it was one in three people in January.
2. Gary Lineker is supporting the Remain vote
Personally I believe there are plenty of reasons to remain, but barely any to leave. Love Europe, love being part of Europe. #Remain

If the EU referendum campaign was to be decided by a winner-takes-all game of football you would probably have to back Remain to take the victory.
Fresh from securing the endorsement of David Beckham and Rio Ferdinand, the Remainers have now been boosted by the support of former England striker Gary Lineker. That's a pretty good core.
3. John Barnes is also for Remain (although Leave campaigners seem to think otherwise).

Sticking with the football theme and Leave campaigners claimed on Tuesday that John Barnes backed Brexit, but the former England winger hit back almost immediately and said he supported Remain. Such was the excitement generated by his endorsement that Lib Dem leader and Remain campaigner Tim Farron felt the need to recreate the famous Barnes rap from World In Motion and post the video on Twitter. Social media gold.
4. There's a whopping £10,000 wager on a Remain result.
How confident are you about the referendum result? Confident enough to wager your own cash? The German tabloid Bild certainly is. It has placed a bet of £10,000 on a Remain result. The best thing about the bet? The newspaper has said it will spend the winnings on investing in "German-British friendship" by buying drinks at a London pub.
5. While the poll prediction results are neck and neck, Twitter is a different story...
The polls have, for the most part, been very close in the run-up to Thursday but apparently things have been different on Twitter. Six in every 10 tweets that have been sent in the last two weeks were in favour of a Leave vote, according to new analysis. More than 2.1 million tweets were analysed in real time by the strategic design consultancy SPARCK, showing a 64% to 36% split for Leave.
