For as long as I can remember, I have been aware of the Democratic Unionist Party, founded by the Reverend Ian Paisley in 1971 and now the largest Unionist party in Northern Ireland.
Now I discover that there is another Democratic Unionist Party (referred to by its members as الحزب الإتحادي الديموقراطي) in Sudan, founded in 1967. I doubt very much that Ian Paisley and Desmond Boal were aware of it when they rebranded and slightly expanded the Protestant Unionist Party four years later, but I shall be on the lookout for parallels as I do my weekend reading of African history.
I’ll have to track that down, but might it not simply be a reference to the fact that some people think Richard III dunnit and some think it was Henry VII?
