TV presenter Holly Willoughby, former England manager Gareth Southgate and Princess Beatrice are among the famous faces taking to the trading floor for charity.
Willoughby, who left ITV’s This Morning last October, joined the BGC Charity Day to fundraise for the children’s charity Together For Short Lives.
The 43-year-old has made few public appearances since a security guard was jailed for life in July over a plot to kidnap and murder her.
Earlier this year, she hosted ITV’s Dancing On Ice along with Stephen Mulhern, and the pair are set to present the rebooted game show You Bet! on the same channel.
At the annual event organised by BGC Partners, she greeted children while dressed in a blue suit and wearing a badge promoting Together For Short Lives, which supports children and young people with life-limiting and life-threatening conditions and their families.
