You have until midnight tonight to register to vote if you haven't already. It's simple and takes about five minutes.
Follow the link to register. It's simple. All you need is your national insurance number, which can be found on any payslip or letter from the Department for Work and Pensions.
If you don't register to vote, then you can't have a say in the general election on 8th June and don't have a say in how your country is run. It's your right, make sure you use it!
