Prince William and Kate to become traders for the day to support charity event

Chloe Best

Prince William and the Duchess of Cambridge, née Kate Middleton, will hit the trading floor on 9 December to participate in ICAP's 23rd annual Charity Day. The royal couple will visit the brokerage firm's London headquarters in a bid to negotiate deals and raise money for causes close to their hearts.

The annual event sees ICAP donate a day's revenue and commissions each year to a number of selected charities. These include SkillForce, of which William is Patron, plus SportsAid and Place2Be, of which Kate is Patron.

William and Kate will participate in ICAP's annual Charity Day

During their visit, William and Kate will be taken on a tour of the ICAP offices where they will meet brokers, as well as representatives from SkillForce, SportsAid and Place2Be.

It will then be the royal couple's turn to close a number of deals over the phone while under the guidance of the brokers.

It is not the first time William will have participated in the Charity Day. In December 2010 the then newly-engaged Prince managed to secure a £14billion deal between two major banks as he manned the phones. However his father Prince Charles was admittedly a little less comfortable in the international trading sphere, confessing he had "no idea" what he was doing.

Since its launch in 1993, ICAP's Charity Day has raised more than £120million for charities around the world, with famous faces including Cheryl Fernandez-Versini, the Duchess of Cornwall and Millie Mackintosh lining up to close deals.

William and Kate have carried out a number of joint engagements together in recent weeks, including a day of mental health engagements in North Wales on Friday. The Duke and Duchess both stepped out of their comfort zones for the day out and showed off their athletic abilities by trying their hand at abseiling.
