I have to agree with my esteemed colleague here.
I interview musicians all the time, and if I repeated a question they had already answered, they would be likely to get up and walk out!
Politicians have to employ more tact and courtesy, but honestly, Kay Burley seemed to be wilfully irritating, confusing inscisive questioning with simple and irrelavent repetition.
One thing I have learned from 35 years of interviewing is that you ask a question, and listen to the response. if there is a development from that answer, then pursue it, and if not, have your next question ready.
It's not that easy, but it comes with experience, something Ms. Burley surely has by now - but you wouldn't think so based on this nonsense!
