Is it a bird? Is it a plane? No, it’s hundreds of brave souls abseiling down a Canary Wharf skyscraper to help raise money for charity.

More than 150 people are set to take a 230ft leap of faith down 20 Cabot Square this weekend – May 7 and 8 - to help raise money for London’s Air Ambulance.

The plucky fundraisers include employees from Santander, HSBC, Citigroup, United Insurance Brokers and Knight Frank.
