The mayor is under pressure to take action to make cycling in London safer after another cyclist was killed on the streets. A man was hit by a bus late last night crossing the Cycle Super Highway in Aldgate East. That means in the past nine days five people have been killed.
Today the mayor defended his bike policy for London and said cyclists need to stop breaking the law in order to stay safe. Our Political Correspondent Simon Harris reports.
