Prince William and Prince Harry took part in the annual BGC partners charity day on Wednesday morning.
The annual event is held each year to honour the memory of the 658 employees who died in the September 11 attacks on the World Trade Centre in New York in 2001 and the entire profits are donated to good causes.
New father William and brother Harry stepped into the role of traders for the morning as they closed deals worth billions hoping to raise money for their charities.
The pair joked with one another as they raised their games for charities WellChild and SkillForce, which the royal brothers support.
“Stop flirting, get on with it,” a cheeky Harry told William at one point.
“He’s on the phone, it’s all baby chat, I’m much better at helicopter chat,” Harry added.
Broker Nick Thompson, 45, prasied the princes for taking the time to stop by. “It was interesting listening to them both to see who was more confident. Harry took to it very well.”
BGC Partners took to their Twitter page to show they were impressed with William’s trading skills.
“Another trade secured by HRH The Duke of Cambridge here at #BGCCharityDay…,” the company tweeted with a photo of the Prince closing a deal.
At one point William was asked how Prince George was doing, to which he replied: “He’s very well thanks. He’s sleeping quite well.”
After attending the event, the brothers rushed to Brentwood, Essex, to join father Prince Charles and the Duchess of Cornwall at the funeral of Charles’ close friend Hugh van Cutsem.
Prince Harry will finish the busy day by attending the ninth annual WellChild Awards, which will take place at the Dorchester Hotel on Park Lane.
