I'm quite bemused by the fact that people think that the faces we see on the TV having a jolly good time at the Kelvingrove Gallery and so on are actually the important people at the summit. The important people are the ones most of us have never heard of; Archie Young, Xie Zhenhua, Teresa Ribera. Not, I'm afraid, Boris, Biden or even the Queen. Biden et all will have to agree to stump up the money, but they don't do the work.
Not quite sure what the Queen's role is. Encourager, maybe?
