Greater Manchester's mayoral election explained
Anthony Parkes/GeographPeople living in Greater Manchester will head to the polls in July to vote for who they think should be the region's mayor.
Residents living in all 10 boroughs will vote in the Greater Manchester mayoral by-election on 30 July.
We take a look at why it is happening, what the timetable is, and how the supplementary vote system works.
Why is there an election?
The election was triggered when Andy Burnham, who held the office for nine years, was elected the MP for Makerfield in last Thursday's parliamentary by-election.
By law, an MP cannot sit in the House of Commons and hold a metropolitan mayor role that has powers over local policing.
What is the timetable?
The Greater Manchester mayoral contest has to take place within 35 days of the post becoming vacant.
The nomination period for candidates for this election runs from 10:00 BST on 26 June to 16:00 on 3 July.
The deadline for voter registration is midnight on 14 July.
To have a postal vote in this election you must apply by 17:00 BST on Wednesday 15 July.
The deadline to apply for a proxy vote is 17:00 BST on Wednesday 22 July.
If you are already registered to vote by post, you will be sent a postal voting pack containing your ballot paper, which should arrive between 17 and 21 July.
If you don't manage to post it in time you can return it by hand before 22:00 BST on polling day to your local electoral registration office or a polling station.
What is the 'supplementary vote' system?
A new voting system will be in place for this election.
The change see a switch from first-past-the-post – which is used in general elections – to the supplementary vote (SV) system.
Under the SV system, voters get to have a first and second choice.
If no candidate wins more than 50% of the vote after first preference votes are counted, the top two candidates will go into a run-off, in which second preference votes from the eliminated candidates are counted.
This system was previously in place for police and crime commissioners and mayors until 2022, when it was changed to first-past-the-post.
