What Richard Bridge said, post of 0622 above.

The only problem with his first point, as I see it, is that under the UK Constitution as it stands, there is no Statute which is not amenable to subsequent repeal.

(Parliament can make or unmake any Law whatsoever; and no person or body is seen as having power and/or authority to overturn or ignore a validly enancted Statute : Dicey, Law of the Constitution).

Hence the principal difficulty in concretising Parliamentary Rules and Constitutional Conventions into Law.

It is claimed that the use of SIs (Statutory Instruments - Delegated Legislation) saves Parliamentary (i.e. House of Commons) time. I would see these done away with.   Legislation which impacts on subjects

of Public Law (you, me, Joe Soap and Lizzie Dripping) should and must be the subject, and the result, of debate on the floor of the House.

(This might give Parliamentarians less time for "Yah ! Boo! Sucks!" abuse.)

Those remaing powers which constitute the Royal Prerogative must be vested in Parliament and not in the PM of the Day, purportedly exercised by the Crown.

The House of Lords must be abolished, and replaces by a small body of directly elected "Senators" (for want of better term).
