Andrew Orlowski's excellent take is here:

Entourages are not something that delegates bring to a conference. Especially if the delegate is a humble public sector scientist. But the private invitation-only event I attended at Downing College Cambridge this week was no ordinary conference. It was an attempt to bring together leading climate scientists and IPCC figures with their critics.

Who, then, had an entourage? Lord Lawson, a splendidly imperial figure, and former Chancellor of the Exchequer, may be expected to bring one, But Lawson had none. University of East Anglia luminaries Phil Jones and Andrew Watson did, however: consiglieres perhaps, taking notes, whispering sotto voce, and fetching the teas and ice cream. They were accompanied by others attached to the Climatic Research unit (CRU) and the Met, whose purpose was not known. It was a beautiful May day. It can't have been for safety, nobody mentioned Climategate all day. The entourages boosted the attendance figures substantially.
