Westminster’s seemingly endless Brexit drama has taken yet another twist with Commons Speaker John Bercow’s ruling that the government cannot bring forward a third ‘meaningful vote’ on its Brexit deal without a substantive change to the proposition. What does it all mean? CCC Fellow Jack Sheldon (Bennett Institute of Public Policy, Cambridge) looks behind the headlines.

Richard Parry traces the way that Geoffrey Cox’s unexpected advice veered the Brexit path off course in three days of Commons votes.

Jonathan Evershed of University College Cork asks whether the UK Government’s new tariff plan is a case of double standards and, if so, why the silence so far from the DUP?

Dr Mary C Murphy of University College Cork explains that the Irish backstop issue cannot simply be reduced to one which pits Northern Ireland's unionists against nationalists. Forces outside of politics, representing a cross-section of society, tacitly support the backstop.

Richard Parry discusses the fraught few days in prospect at Westminster as the Brexit endgame comes into view.
