It is an interesting (re) development how affairs outwith the UK are able to influence affairs within the UK.
Going back to the age of Kings, this was (of course) perfectly normal and everyone knew roughly how to deal with it.
People have (conveniently) forgotten how less than a year ago the wife of the Prime Minister of the United Kingdom was not a UK citizen. Which rather puts any criticisms of a non elected non UK citizen interfering in UK politics into context.
