I think that's his plan, for the first part: sideline Parliament and let Brexit happen while blaming the EU.

For the second, I think he wants to get in on the Brexit feelgood bounce (yes, there will be one, that's how many witless wonders there are in the country), with a comfortable Tory majority and be PM for five years. Someone's got to finish the work Margaret Thatcher started (so says Nigel Lawson, who nose everything).

Things are going to slide, slide in all directions
Won't be nothing
Nothing you can measure anymore
