Not since 1714

Archbishop Cranmer writes that not since 1714 has the UK had a Peer exercising "Soverign Power" in the UK. But as of Monday we do, with Peter Mandelson taking "control" of the UK whilst Gordon Brown takes a holiday and (CRB checks allowing) does some work in the community.

"When Queen Anne died on 1st August 1714, her successor, the Elector of Hanover (George I), was in his German dominion. Baron Parker of Macclesfield was designated Regent of Great Britain, Ireland and the realms beyond the seas until the new King was able to take the Crown. He reigned until 18th September, and was the last Peer to exercise sovereign power...

...until the advent of The Right Honourable the Baron Mandelson of Foy in the County of Herefordshire and Hartlepool in the County of Durham, First Secretary of State and Lord President of the Privy Council and Secretary of State for Business and Secretary of State for Innovation and Skills.

As of Monday, the Royal Prerogative will rest with him."
