Peter Hennessy: On Joining the Constitution

Historian Peter Hennessy discusses joining what he has spent a lifetime writing about: the British constitution.

At a time of constitutional upheaval, what does the second house still provide? He argues that expertise, in rare supply elsewhere in the political system, is abundant in the Lords, and offers a great deal to a system currently held in low esteem.

Four Thought combines big ideas and evocative storytelling in a series of personal viewpoints - speakers take to the stage ready to air their latest thinking on the trends, ideas, interests and passions that affect our culture and society.
