From a pax point of view:
Best: Ian Paisley, very friendly and chatty, didn't discuss politics though but lots of other things to talk about. Peter Mandelson, also friendly.
Worst: William Hague and his 'minder' Seb Coe, both arrogant and ignorant, also very rude to the crew when the departure was delayed due to fog - which anyone would have thought the crew had arranged specially to inconvenience them.
