Point is... the guy is Establishment with a capital 'E' and has stood on both sides of mainstream UK politics. OK, that's not normally a ringing endorsement, but it's fair to say he's going to know a thing or two about Northern Irish politics.

It's an assessment echoed by a lot of voices on this side of the Irish Sea. And not just Republicans. Commentators across the political spectrum are concerned this could blow up in a very unpleasant way.
