London 2012 chairman Seb Coe is refusing to change his mind on the re-routing of the Olympic marathon despite the threat of legal action.
The marathon route was changed to begin and end outside Buckingham Palace, Queen Elizabeth's official residence, after organisers said it would help traffic flow and be less of an impact on other sports taking place in the main stadium and across London.
It will now pass many of the capital's landmarks, avoiding the main stadium in a deprived area of east London.
But one local council, Tower Hamlets, has begun proceedings for a judicial review.
