The Mayor of London's policy is that over a third of flats and houses built on the Olympic Park after 2012 will be affordable.

Boris Johnson's critics, including the Liberal Democrat's Caroline Pidgeon, say it is a broken promise but he insists he is on track to deliver homes Londoners can afford.
