I believe I’d last no more than one question and one follow-up as an interviewer.

“Excuse me, Prime Minister, no. What the people want to hear about is whether you can or cannot sack Johnson. Most think you can’t because, to date, you’ve let him get away with everything. So please stop with the supremely annoying prevaricating your advisers teach you. It’s not as clever as you obviously think it is; in fact, it’s far past tedious. No redirection: Answer the question yes or no first and then briefly explain why.”
