The bottom line is that Boris Johnson is academically and intellectually far brighter than the leaders of any of the other parities and it's beginning to show. Corbyn's academic qualifications are very limited. My wife's cousin who is a recently retired civil servant, a labour voter by the way, informed us that he is not very bright. No surprise there then! I didn't see 'Newsnight' so I can't comment on what was said but my impression of Swinson is that she's not the sharpest tool in the box either. As for Sturgeon, well say no more, she's got tunnel vision, independance.
