Harry jokes with City brokers on trading company's charity day
Prince Harry joked that he was not sure what country he was in as he brokered multimillion-pound deals on a trading floor for charity.
He joined City brokers and closed deals on the phone for global firm ICAP in London, where staff members wore all kinds of fancy dress.
Looking around at the costumes, the Prince told one caller: "I'm not entirely sure what country we're in."
The event comes after the 32-year-old reportedly flew straight to Canada when his Caribbean tour ended at the weekend to be with his girlfriend, Meghan Markle.
He had been due to head back to London but was said to have made the detour to see the actress at her home in Toronto.
Harry was back in the UK in time for ICAP's 24th annual charity day where he sealed big money deals - including one worth 635 million US dollars - and had fun with staff.
After one call, he said the man had told him "I hope to see you soon", and Harry joked: "Sounds like a nice guy ... Not going to happen."
At one point he urged a caller to "stop making small talk" and told another: "We'd like a bit more than that please."
As he moved around the desks and was given help with trading, Harry told staff: "There's no point in explaining to me - I've no idea."
Closing a deal with Bank of Ireland, the Prince signed off his call saying: "Open up a Guinness and have a good day."
On his way out, Harry praised the staff for enthusiastically embracing fancy dress.
"Everyone's made so much effort this year," he said.
All the global revenues from trading during ICAP's charity day will go to a number of causes around the world, including Sentebale, a charity of which the Prince is patron.
Founded by Harry and Prince Seeiso of Lesotho in 2006, Sentebale supports orphans and vulnerable children, many of whom are affected by the HIV/Aids epidemic and extreme poverty.
ICAP is an inter-dealer broker which matches buyers and sellers who want to trade in a range of products, from interest rates to commodities.
Since 1993 its charity day has raised almost £127 million for good causes around the world, with more than 60 ICAP offices worldwide taking part annually.
Celebrities from the world of sport, television and entertainment are also expected to take part.
Sentebale chief executive Cathy Ferrier said Harry was "really happy" to be there, adding: "Basically he wanted to know how the team are in Lesotho. He's always checking up to make sure everyone's all right really."
She said he gets "very involved" in the charity despite his "crazy" schedule.
Before he left, Harry had a go at a game similar to the Christmas children's favourite Operation as staff from London's Air Ambulance looked on.
At the end, the Prince looked down at the life-size dummy, which had a red flashing nose, and said: "That looks like me 10 years ago."
