There have been links between the British racist right and Ulster Loyalists for many years, though as Searchlight magazine shows, the English patsies couldn't compete with the Ulster hardmen, and wielded little direct influence there.

As for Lewes, don't forget that both Henry VIII and Elizabeth I executed more heretics than Mary- though partly due to their longer reigns. Of course the whole reformation period was one of dreadful cruelty and intolerance. But the religious divide in England was not exacerbated by a cultural, linguistic or ethnic divide as in Northern Ireland.
