I don't think it's as meaningful as it first sounded, for instance it doesn't take into account a No Deal scenario. It's more about May limping on and avoiding losing a vote in the HoC, which would probably lead to bringing her down... Open Britain, which is campaigning for a soft Brexit, has put out this statement about David Davis?s announcement. It is from the Labour MP Chris Leslie. He says: What could have been a very welcome concession by the government, instead looks like a sham that pretends to respect the sovereignty of parliament but falls well short of what is required. It?s a transparent and fairly desperate attempt at the eleventh hour to save face and avoid losing votes in the House. Ministers need to do much better. It is crucial that this meaningful vote takes place well before we leave; that defeat for the government?s legislation will not imply leaving the EU with no deal; and that parliament has the same role in the event of a disastrous ?no deal? outcome.
