Yup, and no real friends in the cabinet. Not to mention just pissing off the entire cabinet by announcing a referendum without discussing it with them first. Truly I think we are seeing the last kickings of Mr Blair.
It is fairly vague, the impression I have is that at least three are former ambassadors - of Tel Aviv, Bagdhad and Greece. The others I don't know about. The BBC usually updates as time passes, they tend to get the stories out first (in my experience) and add more detail as it is available, so they may add more details about the people involved later.
That's the impression I get. I have been looking for other sources but cannot find any as of yet.
