A handout picture taken on March 24, 2011 and released by the Olympic Delivery Authority (ODA) press office shows an aerial view of the olympic stadium in the Olympic Park, in east London. A deprived area of London is being rapidly regenerated to host much of the 2012 Olympics in a year, but there are fears the changes may not benefit locals despite efforts to leave a positive legacy. The east London district of Stratford, home to the Olympic Park for next year's sporting extravaganza, was once so filled with smoke-belching factories it earned the unflattering nickname "Stinky Stratford. Since 2005 however, when London was awarded the Games, there has been a frenzy of construction work as the venues went up in the park, with its centrepiece the 80,000-seat Olympic Stadium.
