Who can vote in the elections?
Anybody who is aged 18 or over on 3 May, and who is registered to vote.
If I am 18 or over, am I automatically able to vote?
No. You must have registered to vote. You are not eligible to vote simply because you are the correct age, or because you pay council tax.
Is it too late to register to vote?
Yes. The deadline was Wednesday 18 April.
What if I'm not going to be around to vote in person?
There are two ways you can still take part in the elections - by postal vote, or by proxy vote.
A postal vote has to be applied for in advance. You must fill in a form and send it off. Once you've received your vote, you must make sure you return it in plenty of time for it to arrive before the close of poll (10pm on 3 May).
A proxy vote involves you allowing someone to vote in person on your behalf.
