To say the House of Commons is in something of a crisis would be an understatement. Dozen's of MPs accused of misbehaving, the Prime Minister being investigated for lying to the House and one MP even accused of watching porn in the Commons Chamber.

Dr Hannah White's new book couldn't be more timely. So I talked to her about it. This episode is a little longer, but worth it.

Hannah is Deputy Director of the Institute of Government. Before that she ran the Committee on Standards in Public Life and before that she was a Clark in Parliament. So she is extremely well placed to offer this penetrating analysis of what's wrong, and how to fix it.
