Ken and his cronies top new London power list

An Evening Standard analysis of the top 50 figures in the capital confirms the Mayor in pole position following his role in bringing the 2012 Olympics to London, securing Crossrail, introducing the Oyster card and transforming the bus network.

But what it also reveals is the extent of the power his aides have grasped on his behalf - with people close to him accounting for half the remaining places. Twelve aides directly responsible to Mr Livingstone feature on our list - plus a further 12 over whom he has considerable influence.

The full list of the 1,000 most influential Londoners will be revealed on Tuesday in the Standard. But today we can reveal the 25 who dominate the London political scene.

The five most powerful Londoners as the Mayor, Met commissioner Sir Ian Blair, Transport for London commissioner Peter Hendy, Tube managing director Tim O'Toole and Olympic Delivery Authority chief executive David Higgins.

Mr Livingstone is also in the separate list categories of politics, environment and property. His Tory mayoral challenger Boris Johnson features as an up-and-coming influential, as does likely Liberal Democrat candidate Brian Paddick.

Within City Hall, the list includes the Mayor's ultra-loyal chief of staff Simon Fletcher, long-serving policy directors Neale Coleman (housing and Olympics), John Ross (economics) and Redmond O'Neill (transport) and rising stars such as his climate change guru Mark Watt.

Others who add intellectual vigour, authority and foresight to Brand Livingstone include Lord Rogers, who remains his unpaid architectural adviser, and Bridget Rosewell, consultant chief economist to the Greater London Authority.

Our list, compiled by 40 Evening Standard specialists and independent experts, names the people whose talents have made this the world's most influential city.

Even the Mayor of New York, Michael Bloomberg, admits his envy at London's position - with the billionaire media tycoon itching to return to his second home in Chelsea once his second term ends in 2009.

Speaking this week on a visit to the capital to see the C-charge in operation and the improvements to bus services, Bloomberg said he "had no scruples" about stealing London's ideas. He hopes to introduce "congestion pricing" to Manhattan.

Evening Standard editor Veronica Wadley said London's advances would not have been possible without the people "who not only make the right decisions but have the energy, creativity and power to see those decisions through. They have a profound effect on our lives."
