HARDtalk - Boris Johnson, Mayor of London

Stephen Sackur talks to Boris Johnson, who, as Mayor of London, has the biggest personal political mandate of any politician in Britain. He won the mayor's office for the Conservative party with 1.2 million votes and promised a new vision: to turn London into the world's greatest city. He has had more than twelve months in the job, but that period has also seen Britain plunged into a deep recession. Is he matching his words with deeds?
