PDR, however much you might like it to be, I think you will find that it isn't libel (or slander) to ask a question of an individual.
In any case, you certainly haven't seen the wording of the question asked. Unless you are T C-T herself you won't have - it was addressed to her in person, no-one else.
Nor is it libel or slander to say that the question asked hasn't been answered.
P.s. my blood pressure is OK, thanks. Despite your potentially libellous statement about it being raised.
