On one hand, I think that Boris is flexing he power to prove to [the rest of] Europe that he is willing to take a hard Brexit if the EU is unwilling to negotiate (you can't negotiate unless you're willing to walk away).
On the other hand... This is a complete disaster. If parliament can't function, what hope does the rest of the country have? I think the exchange rate is the best metric on how well Brexit is going. The sad irony is that Brexit was meant to give the UK sovereignty (rule Britania and all that...), but crashing the economy has made everything cheaper for foreign investors. The UK is no longer united metaphorically and literally.
Brexit has been a death march from the get-go.
