There are persistent, quiet allegations that Elizabeth and the monarchy profited from lucrative private investment deals with Muslim nations and businessmen. Covertly, with Elizabeth's acquiescence, much of the British establishment was compromised and opened the country to mass immigration and Islamist subversion.
Will Farage be able to win and save Britain? I hope so, but he will not find the Muslim sympathetic King Charles an ally.
The Royal Family is decadent/corrupt but they used to serve as an effective check on the Parliament years (centuries?) ago.
