The ballot boxes were moved from more than 3,600 polling stations across the capital, staffed by around 12,000 people, to 14 counting centres in the city overnight.But the results are unlikely to be declared until late on Saturday, as verification of the votes does not start until Friday morning at 9am.Counting of the votes then starts at 9am on Saturday, with three ballot papers needing to be counted.The mayoral votes will be counted first, followed by the constituency London Assembly members, and then the London-wide Assembly members.The first results should emerge around midday and it is thought the winner may be clear by as early as 1.30pm on Saturday. But the official announcement is expected to take place in the late afternoon or evening at City Hall – and could be pushed back if there are any delays.This year there was a new voting system, first past the post (FPTP), similar to what is used in general elections.
