Who are we voting for?

All 600 MPs, UK-wide, 73 of which are in Greater London.

The UK uses the 'first past the post' system. This means that our election is actually 600 mini elections in each constituency between people who are usually members of the various political parties (but independents can stand too!). The winner who receives the most votes becoming the MP.

A party or group who gets 301 or more in Parliament forms a majority and becomes the ruling party for up to 5 years.

I still haven't made up my mind!

The main parties standing in almost all London seats are (in alphabetical order):

• Conservatives
• Greens
• Labour
• Lib Dems
• Reform UK

There are a variety of smaller parties and independent candidates too. You can find out who is standing in your constituency by checking here.

Instead of browsing through all the manifestos individually, you can take one of these quizzes which may help:

• Vote for Policies

Or you can choose not to vote, or to spoil your ballot. It's up to you.

Take some ID

The government's Voter ID scheme now requires you to take ID when you vote.

The accepted forms of ID include:

Passport, driving license, blue badge, Freedom Pass, 60+ London Oyster Photocard, Identity card bearing the Proof of Age, Biometric residence permit, National identity card issued by an EEA state, Voter Authority Certificate, and a couple of others.

It doesn't matter if the ID has expired so long as you still look like the photo

I don't have my polling card!

Doesn't matter, just find out where your polling station is and so long as you're registered, you're good to go. Just remember to take ID.

My postal vote didn't arrive!

If you registered for a postal vote but it hasn't shown up, you must request a replacement postal ballot pack in person from your borough council office. This can be done by up to 5pm on polling day, and you must take ID. This will usually be at the town hall or the main council building. Most will offer the option to complete a ballot on site and hand it back to them, ensuring your vote is received.

I moved house and couldn't re-register in time!

You can still vote at your old address, but you will need to physically go to the polling station near there (find it here). Just don't vote twice, that's illegal.

When can I vote?

Polling stations will be open from 7am to 10pm.

If you are in line to vote at your polling station by 10pm, you will be allowed to vote.

How do I vote?

You must be registered. It's simples:

1. Go to your polling station (not sure where? check here)
2. You will be greeted by staff who will ask you address and ID. Hand over your polling card if you have it, it makes this part quicker.
3. You will be given a ballot paper to take to a polling booth (your vote is anonymous).
4. Use the pencil to make a X in the box next to the candidate you want to vote for, or if you want to spoil your ballot, draw an obscene doodle.
5. Fold your ballot paper and take it to the ballot box, pushing it through the slot.
6. On your way out, you may be asked by an Exit Poller or Party Official for your voter number and possibly how you voted. This is not compulsory.

Then the most important part, relocate to a convenient pub, and toast yourself on a job well done.

When will we know the result?

The official 'exit poll' will be published by the BBC, ITV and Sky at 10pm on the dot, as part of their main election news programmes, which will run all night. This should give us some idea of the result, though they can be wrong!

Most vote counting happens overnight on Thursday. We should have the first results by 11:30pm. If one party has a very good night, the result should be clear by around 3am. If it's closer, the result may not be evident until 7am. If no one party receives a majority in Parliament, there will need to be coalition negotiations so the result may not be known for a number of days.

In all likelihood though, we will have a fast transition of power, and the winning party leader will make a speech early on Friday morning and visit the King to officially form a government in the early afternoon, before moving in (or returning) to 10 Downing Street.
