The UK is set to go to the polls in a historic referendum on whether the country should remain a member of the European Union or leave. 
Polling stations are open between 07:00 BST and 22:00 BST. 
An estimated 46,499,537 people are entitled to take part in the vote - a record number for a UK poll. 
It is only the third nationwide referendum in UK history and comes after a four-month battle for votes between the Leave and Remain campaigns. 
The referendum ballot paper asks the following question: "Should the United Kingdom remain a member of the European Union or leave the European Union?" Whichever side gets more than half of all votes cast is considered to have won. 
After the referendum polls close at 22:00 BST, sealed ballot boxes will be collected and transported to the count venue for each of the 382 local counting areas. 
These represent all 380 local government areas in England, Scotland and Wales, plus one each for Northern Ireland and Gibraltar.
