Polling stations open at 7am today for the London mayoral and assembly elections.

The polling stations will stay open until 10pm.

Election organisers said the results will be declared at City Hall, despite the burst water mains on Sunday that flooded the building.

Vote counting will take place at Alexandra Palace, ExCeL and Olympia on Friday.

Once all the votes have been counted, the results for the Mayor of London and the London-wide assembly members will be announced at City Hall.

The constituency assembly member results will be announced as they happen in the count centres.
