With the permission of Bernie Ecclestone the official F1 Party will be hosted by Great Ormond Street Hospital Children's Charity for the third year running.

This year the Party is supported by the British Grand Prix title sponsor, Santander, and will take place at The Worx, Parsons Green, London, SW6 on Wednesday 4 July at 7.30pm.

McLaren driver Lewis Hamilton is one of the confirmed guests, along with team principal Ron Dennis, Giancarlo Fisichella and Heikki Kovalainen. Celebrities attending the event include the charity's patrons Tess Daly and Vernon Kay as well as Geri Halliwell, Rupert Everett, Thandie Newton, Tamzin Outhwaite, Lemar and Robert Kazinsky.

This evening will celebrate the hospital's relationship with Formula One and hopefully raise vital funds to build a new Heart and Lung Centre.

"I'm really looking forward to going to one of the most glamorous, exclusive and important evenings in the annual F1 calendar," said Hamilton. "Alongside Bernie Ecclestone, Santander and the Formula One community, I am extremely proud to be lending my support towards this immensely deserving cause."

Great Ormond Street Hospital Children's Charity is Mr Ecclestone's official charity for the British Grand Prix and every year many of the hospital's patients are invited to enjoy the event from the Paddock, where they get to meet their F1 heroes.

High profile guests have been exclusively invited to The Worx to enjoy food designed by Gordon Ramsay and chefs from his stable of restaurants, music will be provided by celebrity DJ Michael Adam with an acoustic set by Jamie Scott and The Town.

On the night there will be an auction with money-can't-buy lots on offer. Highlights include a lap before the start of the British GP in the Santander Abbey 2-seater Grand Prix car driven by Damon Hill; two temporary positions at the Spyker team at this year's Santander British Grand Prix - a once in a lifetime chance to enjoy work experience in an F1 pit stop - a 1:4 scale model of the 2007 McLaren MP4 22 signed by current world champion Fernando Alonso and Lewis Hamilton, as well as a limited edition of 'F1 - The Opus', signed by the sixteen living Formula One world champions.

Dr Allan Goldman, cardiac intensive care consultant at Great Ormond Street, explains: "You could compare our current facilities to driving an F1 car - but on a gravel track. With the support of the 2007 Formula 1 Santander British Grand Prix we aspire to drive on a track as high quality as Silverstone."
