SO WHAT HAPPENS NEXT?
NO10 fear that Theresa May’s premiership could implode on Tuesday night if the scale of her defeat is insurmountable, with aides and allies braced for two doomsday scenarios:
FEAR ONE: If Theresa May’s bill is heavily defeated, Labour is likely to call a confidence vote in the Government on Wednesday. If the Government loses heavily, Mrs May will resign; if it wins, she will likely head to Brussels immediately for crisis talks.
FEAR TWO: Cabinet Remainers could join with Labour to hamstring the Prime Minister by hijacking her Immigration Bill to demand the UK stays in a Customs Union with the EU forever.
It would likely spark a devastating backlash from Brexiteers that could yet topple the PM’s wafer-thin grip on power.
