Should the UK have a written constitution?

An eventful week in British politics has been dominated by proceedings at the Supreme Court where judges have been listening to arguments over whether the Prime Minister acted lawfully in suspending Parliament. Adam Boulton and guests discuss the hearing and its potential consequences, there's a look ahead to the Labour conference in Brighton and reflections on the Lib Dem gathering Bournemouth where Jo Swinson came out in favour of scrapping Brexit altogether in the event of her becoming Prime Minister. Joining Adam this week are the director of the Demos think tank - and former Special Adviser to Nick Clegg - Polly Mackenzie, the General Secretary of Labour Leave Brendan Chilton and Sky's political reporter Rob Powell.
