About 46.9 million are registered to vote, this is up from the last general election in 2015, when 46.4 million were registered. 

The snap poll was called by the Prime Minister just seven weeks ago, when she made the shock announcement on April 18. 

Following recent attacks terror attacks in Manchester and London, security around polling stations is being closely monitored.

Metropolitan Police Deputy Assistant Commissioner Lucy D'Orsi acknowledged that the General Election is taking place during "unprecedented times".

"Security around polling stations is constantly being reviewed and updated by local police forces... We continue to ask the public to be alert and to report any concerns to police."

This will be the first General Election in the UK where campaigning was halted by terrorist attacks.
