What does the UK want from the EU?

Dominic Raab, the recently appointed Brexit Secretary has been in Brussels this week - his first visit since replacing David Davis, who resigned after the cabinet had apparently agreed on a document that represented a UK proposal for its future relationship with Brussels. The Chequers document was the basis for the White Paper presented by the government last week, but the White Paper was undermined almost immediately by two days of dramatic interventions in parliament. So is what was agreed at Chequers really the basis of the UK's negotiating position? David Aaronovitch discusses this week's political and technical developments.CONTRIBUTORSAdrian Wooldridge, political editor of The Economist and author of the Bagehot columnJill Rutter, former Treasury and Number 10 civil servant and now programme director at the Institute of GovernmentPatrick Smith, Europe editor of the Irish Times
