Via Wolfgang Munchau:
The gloves have come off on both sides. MPs are now plotting a strategy to take total control of the House of Commons, and anti-Brexit Lords have devised a strategy to frustrate a filibuster. The important question is not whether a legislative route is theoretically possible within the time limits – we think it probably is – but whether the rebels have the votes, and if they do, whether such legislation is effective. On the first, we don’t think they do. On the second, we are sure that it is not.
…There is a lot of arm-twisting going on in the background – coupled with the implicit threat that a vote in favour of anti-Brexit legislation would most likely trigger elections and the certain deselection of Tory rebels. Tories and Labour MPs are both aware that extension is not a popular option in the country. The April extension brought victory to Nigel Farage’s party in the European elections in May. If parliament votes in favour of a law to extend, it is possible that Johnson would then risk a pre-Brexit election, with the support of Corbyn. We think he will probably do at least as well as Theresa May did two years ago, but with MPs that are committed to his Brexit strategy.
