I suspect you are right, Steve, that anything other than a complete exoneration will lead to Starmer standing down. But a tactical measure I think leaving this uncertain will tempt the unwary Tory MPs to try to make him commit, which actually just makes Johnson's position look weaker. It has a cost of the media asking incessantly, but maybe they reckon the is a price worth paying to have the less attentive MPs calling for him to quit. Some are attempting the awkward balancing act saying no one should resign over the fines but if Starmer wishes to it is up to him.
