Dominic Gover live at City Hall:

The expected result is confirmed. Boris Johnson is Mayor of London.

23.45

Officials to announce result "in minutes".

23.35

All but one of the constituency results are in and Boris Johnson is ahead on constituencies by seven to six. A declaration is due soon.

23.30

Boris Johnson wins West Central constituency.

23.00

Boris Johnson is favourite to win Havering and Redbridge, pending second preference votes.

Ken Livingstone is in a strong position in Enfield and Haringey, and barring a strong show of second preference votes for Boris, he is looking likely to win in the north London constituency.

21:54

The results for the mayoral ballot in the north east constituency (including Waltham Forest) are in. This includes first preferences only:

BNP 3,778

UKIP 1,396

Green 9,790

Boris Johnson 57,394

Ken Livingstone 96,402

Winston McKenzie 482

English Democrats 820

Brian Paddick 19,641

Christain People's alliance 3,067

21.50

"I think a lot of people will have voted Tory, possibly for the first and only time in their lives, to punish Ken's machine for its cynicism, and Labour generally for its comfy insulation from its roots in the lives of ordinary people. (mdj, E10)

21.10

Tessa Jowell concedes defeat to Boris Johnson.

The minister for London ran Ken Livingstone's election campaign.

Jowell calls for a new culture in the Labour party.

She said: "It remains to be seen whether this result reflects a sea change in power across the country. I hope there is no chat about Gordon Brown"

21.04

The Evening Standard has run a front page stating that Boris is mayor. Speculation is rife as to whether he will, if he wins, have the required two-thirds majority in the London Assembly that the mayor needs to get his budget passed into statute.

20:40

The trickle of media personalities who made themselves available for interview earlier in the evening has dried up. Perhaps they are in their respective party's campaign headaquarters with a flute of champagne, watching the television, like the gathered media here, in the heights of 'The Egg'.

19:52

There is a whisper going around that the BNP are close to winning two seats in the Constituent Assembly. Proportional Representation looks like its working for the extreme right.

19:48

Ken has stretched his lead over Boris in the vote for mayor in Enfield and Haringey. 98 per cent of votes have been counted.

19:28

The latest rumour is that Boris is ahead by 48 per cent to Ken's 41 per cent overall. This means the Conservative candidate is three per cent away from winning the mayoral race straight out.

A candidate requires parity, which is a clear majority of 51 per cent for this to happen.

There would be no need for a run-off if parity is reached by a candidate.

19:10

The constabulary is guarding democracy vigourisly. While the count progresses in the bowels of City Hall, a rag-tag bunch of 10 anti-fascist protesters have been herded into a pen on the walkway by the river Thames. About 40 police officers have formed a ring around the pen's perimater.

A police boat is on the scene too, maybe to prevent the protesters from getting any ideas about requisitioning the docked HMS Belfast. Fat chance.

19.05

87.62 per cent of votes are counted in Enfield and Haringey, and Ken has a narrow lead over Boris. Enfield has flitted between the two throughout the count.

The pollsters say that turnout is high in the constituencies where Boris is performing well. Could it be that apathy does for Ken in the end?

The old Etonion currently holds leads in eight of London's 14 constituencies.

18:54

Some pointless, or perhaps presicent, trivia. Today is the feast day of St Boris in the Bulgarian and Greek orthodox church.

Will his namesake move in mysterious ways? Will he be required to? Or will Ken's army be too strong?

18:47

Result expected at '10pm at the earliest' according to one official.

The reason for the delay is that an extra 1.5m people voted. Altogether, 7.2m papers have to be counted. This means that 2.4m people voted in the election for mayor of London.

17:55

It seems that Ken's lot is so low right now, that even vanquished foes from elections past believe they could chase him out of town tonight.

Steve Norris was beaten by Livingstone twice in the race for mayor, in 2000 and 2004. But the Tory's ex-candidate believes that it would be third time lucky for him.

Mr Norris said: "I would love to run this time because I would have beaten him. But I cannot afford it. I could have done eight years ago."

17:21

We are told that the winner will not be announced now until 10.30pm. So much for the march of technology. Electronic counting was supposed to quicken the process. It may be a typical, traditional election night after all.

Tessa Jowell, the minister for London, seems to be preparing for the worst.

She said: "I've heard that Boris is ahead.

If Ken has not won, London has lost someone special. He has been passionate for the city and has done great things, and that is something I have heard all across London.

"But we are not there yet, and we may be in for a long night.

"There has been a move against the government, and London is not immune to that."

"People in London are worried about the big turbulence and how it will affect them"

I think that in london it has been a contest between two big figures. Although it has been a close contest, we cannot take the influence of the bad night we had last night"

"It's not fair to say that the party is dying. Ken Livingstone has galvanised the party base against the BNP."

16.45

Mr Paddick is doing interviews in the media gallery. He does not have the demeanour of a man preparing for office and appeared irked by some questions. He also did not seem to give much credence to the gossip.

Commenting on the speculation that the race would be between him and Mr Johnson, he said: "That would be a turn up for the books. It is early days yet, but it is clear that a lot of people are voting against the government. The elections so far have been a disaster for Labour. It's not the Tories who have gained from that."

The North East constituency is one of the five where he is ahead. He currently holds a strong lead there.

A rumour is racing around the media gallery that the race for mayor will be between Boris and Brian Paddick.
