The Duke of Cambridge and Prince Harry tired their hands at stockbroking in a bid to raise money for charity.
William and his brother will join traders at BCG Partners in London’s Docklands to make big deals over the phone for the event, which is in memory of people who died on September 11.
Brokerage firm BGC, which lost 658 employees in the attack on the World Trade Centre in New York 12 years ago, has raised more than 89 million dollars (£56 million) for charity since it launched its charity day nine years ago.
As well as William and Harry, BGC Partners has also invited celebrities including Helen McCrory to the British summer theme party.
All money generated will be donated to good causes, including SkillForce, of which William is patron, and WellChild, of which Harry is patron. BGC lost 658 employees in the attack on the World Trade Centre 12 years ago, and its annual Charity Day, now in its ninth year, has so far raised more than 89 million dollars.
The Princes each made a handful of high-value deals during their 50-minute visit. At first they appeared a little timid, but they soon got into the swing of things.
