(who I assume to be) the most radical conservative member of Parliament

Yes, I guess, although Northern Ireland politics is so utterly polarised by the Northern Ireland question itself that those parties seem to be seldom plotted on the same axis as the right/centre/left of mainland politics. That was a slightly throwaway joke about Paisley and Union Jacks, although like other hardline Unionists in Northern Ireland his enthusiasm for Britain is colossally greater than Britain's enthusiasm for itself, and you'll see more Union Jacks on display in any one loyalist street in Belfast than you will in the whole of London. Plus royaliste que le roi, je pense.
