Who governs Britain?

The former President of the Supreme Court, Lord Neuberger, questions how senior judges became cast as 'enemies of the people' last year. He tells Andrew Marr how the judiciary has grown more powerful and ready to challenge the government over the last half century - while professor of politics Tim Bale explores whether parliament has at the same time become weaker. Cicero was proscribed as an enemy of the people in the 1st century BC. Robert Harris's Cicero trilogy has now been dramatized for the stage, and is a timely reminder of earlier collisions of politics, the law and the people. Barbara Hosking understands the workings of politics and the media, having served under two Prime Ministers - Harold Wilson and Edward Heath - and pioneered breakfast television. She reflects back on her life travelling from a Cornish village to the corridors of power. Producer: Katy Hickman.
