As a past attorney general I consider a WTO Brexit to be a disaster for us as, leaving aside the economic damage it will cause, it would trash our reputation for observing our international obligations - as it must lead to our breaching the Good Friday Agreement with Ireland on the Irish border.
Trade wars in which countries are then obliged to retaliate by raising their own tariffs against the initiator undermine growth and hurt consumers. Far from being expressions of strength they highlight the failure of the initiating country's economic sector to compete in the global market place.
The purpose of the E.U. Withdrawal Bill is in any event not to decide the terms of Brexit but to ensure that it can take place smoothly and that legal continuity, which is essential for businesses, is maintained. There is not a single MP who does not agree that getting the bill on the statute book is essential for us all.
