ICYMI, London will know who their new mayor will be for the next four years by about 3pm on Friday.
The Conservative and Labour party choices - Zac Goldsmith and Sadiq Khan - are predicted as front-runners. But who else is vying to replace Boris Johnson in the elections on May 5?
Londoners will get two votes in the election - they will be asked to mark their first and second choice of candidates on the ballot paper.
They also get a further two votes for the London Assembly, which scrutinises the activities of the mayor and holds him or her to account.
