Weymouth youngster Adam Sevenoaks joined celebrities to close multi-million pound trades, as part of a Julia's House charity day out to Canary Wharf.

Brave Adam, 12, from Sutton Poyntz, was diagnosed with Duchenne muscular dystrophy in 2010, a severe condition which leads to paralysis.

Global brokerage company, BGC Partners, hosts the annual star-studded charity day to commemorate the lives of more than 700 colleagues and employees who died in the 9/11 attack in New York.

The celebrity ambassadors took to the trading floor in the London office to raise money for some amazing causes, including Julia’s House.

BGC Partners donates 100 per cent of the global revenue from the day’s trading to the charities and the Cantor Fitzgerald Relief Fund.

Adam was joined by Joseph Hartley, seven, from Wiltshire, and Julia’s House celebrity patrons Martin Clunes, Harry Redknapp and Debra Stephenson.

The boys got the chance to take part and learn about trading first-hand – as well as autograph hunting from the A-list guests.

Adam's mum Mary Sevenoaks said: "The event was amazing, Adam loved the trip and was honoured to be asked to represent Julia's House.

It was a very special day.

"He did a trade on the phone and I think the company, BGC Partners, thought that he was the most polite trader they'd seen because he said "thank you" and "bye" when he ended the call.

"The staff at BGC were absolutely lovely, really excellent with the kids."

Among the celebrities representing charities this year were Frank Bruno, Olly Murs, Claudia Winkleman, Spurs manager Mauricio Pochettino, Ryan Giggs, John Terry, Damian Lewis, Helen McCrory, Bill Nighy, Holly Willoughby and Tom Hardy.

Adam's mum said: "He loved meeting the celebs – particularly Spurs manager Mauricio Pochettino.

I'd like to say a 'big thank' you to Julia's House for inviting Adam, and BGC for putting the event on."

Julia’s House will be using the funds to support its teen project to enable young people with life-shortening conditions to access its teen club, outings and shared experiences, enabling them make new friends and build confidence in the challenging teenage years.
