His opinion is consistent with that of other Brexiters. There was a survey a few months back and 70%- ish (can't recall exact figure) of Brexiters, if between staying or leaving the EU and having Northern Ireland leave the UK, chose leaving the EU.
Quinny wrote: No, that date was never fixed in law. TM, DD and BoJo pushed for it, but that amendment was withdrawn thanks to the Tory "rebels". Dominic Grieve et al could see for a need to extend the time period under Article 50, which couldn't be done if the 29th March was fixed. And, given that the rest of the EU really doesn't want the UK to leave, if there was a request to extend the A50 period for a second vote, they'd more than happily approve the request.
At the end of the day we are a parliamentary democracy and Parliament has the collective power to prevent the UK crashing out without a deal. And I think there's a change coming whereby Parliament will not accept two options to vote on: TM's awful Chequers Agreement or no deal. I think some waiverers in The House may have taken attention of 700,000 marchers in London yesterday.
