Boris is doing what he needs to do to get elected, to get the top job as its all he cares about. So he was staying quiet not to piss the MPs off with an inevitable gaff and then saying what he thinks Party members want to hear. He knows very well that he wont get a no deal through without some kind of constitutional shenanigan. But will cross that bridge when it comes. He is just saying whatever is needed to advance his own career.
Oh hang on when did he last do that.... lying ****
