Well it's all getting interesting,
Boris has stated he will not deliver Corbyn's "Surrender Bill" to Brussels. I've read he will simply not ask for Royal Consent, which is required for this type of bill.
But, cunningly, he will inform parliament beforehand and allow, if not call, a Vote of No Confidence in his own Government.
Thus leaving parliment two options,
1, Vote in favoir of the Government and in doing so allow Boris not to deliver the "Surrender Bill" and a No Deal Brexit follows on the 31st of October.
2, Vote " No Confidence" and force a General Election and either Torry/Brexit Party romp home with a majority or there is simply insufficient time and a No Deal default occurs on 31st October.
Looks like Brexit may be happening at last.
