At the time of writing it seems unlikely that the Withdrawal Agreement will be accepted by Parliament on 29th March, the day originally set for the UK to leave the EU. Parliament has decided that in these circumstances it will hold a further round of voting on 1st April, in the hope of arriving at a consensus on Brexit after the indecisive votes of 27th March. It is entirely possible that on 1st April a majority of the House of Commons will vote for permanent British membership of a Customs Union with the EU or for a further referendum. This will bring great political satisfaction to those MPs who since the beginning of the year have been arguing that Parliament should “take control” of the Brexit process.
UPDATE 25/03/19: Last week the European Council gave the United Kingdom two further weeks to come up with a plan for avoiding a “no deal” Brexit. It is now up to Parliament to adopt such a plan and make the government adopt it too. If this government remains set on “no deal,” Parliament needs to replace it.
It is frequently claimed that the central flaw of the 2016 European referendum was its failure to clarify the nature of the Brexit for which Leave voters were voting. There is some truth in this analysis, but it does not precisely capture the inadequacy of the result as a basis for subsequent action. Many, probably most, Leave voters had a clear idea of what they thought they were voting for: maintenance of the economic benefits of EU membership, coupled with the disappearance of the legal and political obligations arising from that membership. The Leave campaign spent much time and effort presenting this seductive and dishonest prospectus to the electorate. Indeed, they would not have gained their narrow victory if they had spoken frankly of the unwelcome trade-offs that would inevitably accompany Brexit.
