Today hundreds of protesters gathered in London’s financial district today to call for a clean-up of the banking system and an end to hidden bank fees led by disruptive tech startup TransferWise. The demonstrators, wearing bathrobes, drove engine-powered bathtubs around Bank and blew millions of bubbles over London’s skyline. The protest calls on financiers to stop misleading consumers with sneaky fees. 6,000 blue rubber ducks were scattered across the City to mark the occasion.
