The Brooklyn Brothers has been briefed to create an international campaign promoting London’s Olympic legacy that will run in key tourism markets in 2013/14. It will be the capital’s main promotional message to tourists.

Jackie Stevenson, a managing partner of The Brooklyn Brothers, added: "This is every London agency’s dream brief, to work on promoting this amazing city of ours.
