Baking queen Mary Berry proved to be a tough cookie on the trading floor as she joined celebrities to take part in an annual charity day.

The Penn resident joined in at BGC Partners’ charity day in Canary Wharf on Monday as a patron of Child Bereavement UK, which was one of the company’s chosen charities.

Mary charmed brokers to make sure her deals got a good rise.

It was the company’s 13th annual BGC charity day which commemorates the 658 Cantor and 61 Eurobrokers employees who lost their lives in the World Trade Centre attacks in 2001.

Bereaved families supported by Child Bereavement UK were also invited to join in the fun, and took part in the Paddington Bear themed activities laid on by BGC for the families helped by the various charities.

Child Bereavement UK’s chief executive Ann Chalmers said: “It was wonderful to be represented by our patron, Mary Berry, who was a great sport and proved to be a natural on the trading floor too.

“We are incredibly grateful to BGC for choosing Child Bereavement UK as one of their beneficiary charities.

“It is a very positive way to remember those who died at the World Trade Centre by raising funds for good causes, and we are privileged to be a part of it.

“The day will be a great boost in helping us to raise much-needed funds and awareness, to ensure that we can support many more families to help them begin to rebuild their lives after bereavement.”
