Hmm. That seems really alienating, to me. The MP asked a good question, in that, it's one lots of people have, and if you ask a question, there's an opportunity for it to be answered.
Whitty did answer it comprehensively, but should have lost everything before "The reality is..." The contempt he displayed initially is only going to drive people further into their corner.
(In case it's not clear, the question asked isn't one I have, and I agree completely with what Whitty said, but what I mutter to myself doesn't have the same impact.)
