I think it would be more beneficial if the UK was represented by someone who is a) democratically elected, therefore accountable b) intelligent c) culturally sensitive and d) doesn't come across as an arrogant bore.This is a trade envoy, not a minister. Should we elect all our trade envoys? Who would be the electorate? Expats who might get embarrassed by their behaviour?
b) Never met a thick helicopter pilot, maybe there are some, but not in my experience. No he isn't the greatest academic, never was, but not thick.
c) He was with a group of British businessmen. That is culturally sensitive to them. When with the Kyrgyz types he is culturally sensitive to them.
d) Well fine, there you have me, but again I would say he was with an audience that appreciated it. Except the US ambassador who seems to have responded like a junior Jean Brodie.
I wouldn't worry, if he was representing the UK in that matter at the Cultural olympiad I would have thought it rather inappropriate, but here there should be no real problems.
The big question is, did British business pick any good contracts on the trip? If not then he failed, if so then he didn't.
