EU referendum: How to register to vote
Time is running out to register to vote in the EU referendum.
People have until just before midnight on Thursday to sign up for what many believe is the most crucial vote in a generation.
Here's how to ensure you don't miss out.
When is the referendum - and what's it all about?
The referendum will be held on June 23, 2016.
It will ask the question:
You will have to cast a vote to 'remain', or to 'leave'.
Am I allowed to vote?
You must be aged 18 or over on the day of the referendum, and registered to vote.
You are eligible to vote if you are:
* A British or Irish citizen living in the UK, or a Commonwealth citizen living in the UK with leave to remain (or who does not require leave to remain)
* A British citizen living overseas, who has been registered to vote in the UK within the last 15 years
* An Irish citizen living overseas who was born in Northern Ireland, and who has been registered to vote in Northern Ireland in the last 15 years
How do I register to vote?
You now have until just before midnight on June 9 to make sure you're registered to vote in the referendum.
For those living in England, Scotland or Wales, the online registration system means it's easier than ever.
Just fill in your details here - it takes under five minutes, and then you're done.
British citizens living abroad who meet the eligibility criteria can register the same way.
For those in Northern Ireland, you will need to download a registration form and fill it out.
How do I know if I'm already registered to vote?
If you're not sure, check your local authority's electoral register. There is no online electoral roll so you will have to contact your council's electoral registration office.
Enter your postcode here to find the right contact details.
If you are a British or Irish citizen born in Northern Ireland, contact the office for your last UK address.
Where and when will polling stations be open?
Once you're registered, you will be sent a polling card which will contain details of where your polling station is.
You will also be able to check this online closer to the date of the referendum.
The polls will be open from 7am until 10pm on June 23.
What if I won't be able to get to the polls on the day?
If you know you won't be around on the day - if you're a student, for example, if you're on holiday or if you're casting a vote from abroad - you can register to vote by post.
Download the form here - and make sure it arrives at your local electoral registration office by 5pm on June 8, 2016.
A ballot paper will be sent out by post and must be returned by 10pm on June 23, 2016; so if you are overseas and considering this option, make sure you allow plenty of time for it to arrive.
There is also the option of voting by proxy - ie allowing somebody you trust to vote on your behalf.
There are different forms available depending on the reasons for your application, including disability, educational, employment, and being overseas. Find the right form here. This must be returned to the local electoral registration office by 5pm on June 15, 2016.
Both of these options do have to be done in advance, however. If you don't register for postal or proxy vote and can't make it on the day, you will miss out on having your say, so consider the options carefully.
