I share your positivity re Keir Starmer but he isn't actually nailing the blonde bomber, is he? What he should have done yesterday was put the ball in the net by asking a one-off question: have you read the report, yes or no?
The problem is that he's a lawyer and whilst that arms him fully for the debate, it falls short of making Bozzer look a complete tool. To achieve that, he needs to use humour effectively.
