Take a stroll through London's financial district on a normal day, and the dress code is predictable: tailored suits, polished shoes, and briefcases. This week, thanks to the relentless heat wave baking Europe, some workers have been arriving in Speedos.While many people working in Canary Wharf — a purpose-built East London office district home to banks, investment funds, and law firms — have air-conditioned offices, they now have a new option to stay cool.Floating in the shadow of Canary Wharf's giant glass and steel skyscrapers is Eden Dock, where you can visit Sea Lanes, an open-water swimming pool filled with the dock's natural spring-fed water.On Thursday, when temperatures hit the mid 90s, a mix of chefs, doctors, office workers, and freelancers were queuing for one thing: somewhere cold enough to cool down.'By the end of the day, you don't know who you are anymore'

Renee, 24-year-old chef, said she was looking for somewhere to escape the heat of the kitchen.
