1.55am - The City of London count is announced as vote to Remain in the EU.
2am - Bookmakers change their odds in favour of Leave winning the referendum, with Ladbrokes putting odds of 1/2 on a Brexit result. Having had an 86% chance of Remain winning at the close of polls, the odds have shrunk to 6/4, or 38%.

3.27am - Sheffield comes out for Leave, backing an exit from the EU by little over 5,000 votes.

4.05am - Ukip leader Nigel Farage appears to claim victory in the EU referendum, saying: "Let June 23 go down in our history as our independence day". He calls the votes for the Leave campaign "a victory for real people, for ordinary people, for decent people", and asked if David Cameron should resign if the UK votes for Brexit, he replies: "Immediately."
4.13am - People in Wales vote to leave the European Union, despite a Remain win in Cardiff.
