Earlier today, armed police shot dead a terrorist on London Bridge, but not before he stabbed several people with two kitchen knives.
So far his identity hasn’t been revealed, nor indeed even hinted at. That leaves room for guesswork, which is what I’m inviting you to try.
On the balance of probabilities, do you think the attacker was a) a Tory-voting Englishman, b) a Labour-voting Muslim or c) an apolitical other?
Remember your answer to this question and check the test result tomorrow, when, one hopes, we’ll find out.
