Re: Regardless of which side of the fence you are on.
"Normally, the inability for Parliament to act in this situation would result in an election has been the historical solution."
Elections have been known to give rise directly to the current situation*, namely a Parliament without an overall majority. In those circumstances an immediate further election is the last resort; normally there's an attempt to form a coalition or possibly a temporary government of national unity.
In the present circumstance May and BoJo have attempted to run down the clock to one of other Brexit that MPs as a whole either don't support for personal reasons or think is against the long term interests of the nation. That has produced a crisis situation in which case an election is untenable. The timing of it would present the incoming government with a dog's breakfast for the management of which he or she would be responsible.
* In fact the last election did just that. May only got a majority with the aid of DUP. The change since than is that what with MPs deciding to follow their consciences and what they considered to be the best interests of their country to change parties and BoJo chucking more out of "his" party, even that majority has gone.
