The Evening Standard will reveal its annual list of the most influential people in the capital on September 19.

Mayor Boris Johnson will be the guest speaker at a glittering party to celebrate the publication of The Power 1000: London’s Most Influential in association with Battersea Power Station.

The event will be the last major party to be held at Battersea before the site is transformed into a £8 billion, 39-acre residential and office complex, one of the most ambitious redevelopments seen in the capital. Soul singer Andreya Triana and jazz band Tomorrow’s Warriors are among the musical talent set to perform.

A panel of specialist Evening Standard reporters and critics picks the list, which recognises the most influential people from every walk of London life — from high finance to theatre, from politics to technology.

Evening Standard editor Sarah Sands said: “London’s Power 1000 is not a fixed and predictable list. It changes to reflect shifting fortunes and talents in a crucible of creativity where great ideas are as likely to come from individuals on laptops in coffee shops as from large corporations.”

After the global excitement surrounding the birth of Prince George, this year’s edition of The Power 1000 has a new section called Ambassadors, which features the Londoners who are standard-bearers for the capital around the world.

Movers & Shapers focuses on the developers, architects and engineers who are transforming the capital above ground and below — from Battersea in the west to Tech City in the east, with Crossrail underneath it all.Last year, Mr Johnson was named the most influential Londoner in The Power 1000 when he eclipsed Prime Minister David Cameron after the two men shared the title in 2011.

The Evening Standard panel felt the Mayor’s stature had grown after his re-election and his role in the 2012 Games. With Mr Cameron under pressure at Westminster and the Mayor facing fresh challenges at City Hall, this year’s Power 1000, the seventh edition, could produce some surprising results.

The Power 1000: London’s Most Influential in association with Battersea Power Station will be published in print, online and on tablet on Friday September 20.
