London cycle deaths: Renewed calls for lorry ban

There have been renewed calls for lorries to be banned from some of London's roads at peak times.

It comes after the deaths of six cyclists on the capital's streets in the last two weeks.

Restrictions are already in place in Paris and Dublin, but some campaigners say it is the layout of our roads which needs to change.
