Olympics boss Lord Coe prepares to face questions from the London Assembly.
Although London 2012 was hailed a success, this week the organisers of the Games will face tough questions about what they did right, and what they got wrong.

He will be under pressure to defend his organisation.
He is also likely to be quizzed about the unresolved future of the Olympic stadium.
