sazzi, There is no question of deserting the government, it is a question f ditching the current leader.
The leader is not the party, which is something BJ has not fully grasped. Boris did not win the last election, the Conservatives did, and they can win again, but not with the current leader.
If Boris had any honour, and not just naked self interest. he would see that he was the proverbial millstone round the Conservatives neck and step aside voluntarily. But of course, for Boris, only Boris matters.
I am not a Conservative voter, never have been, but I think that once Boris goes and they have a leader of principle - and their are principles Conservatives.
It is like when jeremy Corbyn led the Labour party, many opposed him, and realised their time would come, in the meanwhile they deliberately faded into the background, to reappear when Corbyn went.
