The Electoral Commission and the British Embassy widely publicised theadvisorydate to register to make sure people had time to get and return a postal vote, however theactualdeadline is midnight of June 7. Britons living abroad are able to apply by proxy also until 5pm on the June 15.
An Electoral Commission guide for overseas voters (attached) says “UK citizens living overseas should apply to register to vote by May 16 2016”. The reason for this was to ensure enough time for the postal votes to be sent and returned, however there is also the option of voting by proxy.
There are four days left for Britons in the UK and abroad to register and it would be a huge shame if they did not get to have their say.
