The clown prince traders: Princes Harry and William go for broke to land £21bn mega-deal

Princes William and Harry cracked jokes as they made a record-breaking multi-billion pound deal for charity on a City trading floor.

As the brothers brokered the £21billion trade, Harry teased his brother for being obsessed with ‘baby chat’.

They were at BGC Partners in London’s Docklands to raise money in memory of people who died in the 9/11 attacks in 2001.

At first they appeared a little timid, but they soon got into the swing of things as the raucous trading floor buzzed around them.

‘He’s on the phone and it’s all baby chat,’ said Harry. He then turned to William and said: ‘Stop flirting, get on with it.’

At one point William remarked to a broker: ‘Bloody hell, was that a billion?’

After the trader nodded, he turned to Harry to say: ‘Apparently we should work here.’

During one of his deals, Harry urged the trader on the end of the line to put up more money. ‘150? Why don’t we make that 200?’ he said. ‘200? Done.’

The last deal the brothers made was for £21billion, a world record for a forward foreign exchange.

BGC broker Nick Thompson, 45, from Otley, West Yorkshire, mentored Harry through the deal he made alongside William. ‘He was great,’ he said. ‘He’s very laid back about it. He did very well.

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 £56million.

Other celebrities involved included the actress Anna Friel and Baywatch star David Hasselhoff, who brought a bikini-clad friend.

The event was compered by comedian Jimmy Carr.
