I certainly agree that it needs to be well worded.
I am pleasantly surprised that people have taken to this subject. Usually some bizarre form of patriotism makes the British defend their system, where it seems undefendable to most other countries.
For starters the Magna Carta has been mentioned, and this as well as the Bill of Rights in 1688 both are agreements between the Monarchy and the Parliament, NOT an agreement between the Parliament and the People.
The statement that a good parliament doesn't need one and that a bad one makes one worthless is facile and not true. In both cases a Constitution or Bill of Rights would, if written well, limit the bad effects.
Also if we had Constitutional Courts then the law system in the UK would be much simpler and less expensive. Though this might suggest the lack of support from lawyers for this idea.
I accept the criticism that mostly I am talking about a Bill of Rights. I am. However i feel that writing down the mechanism of government contributes to open government.
The key would seem to create a mechanism where anyone can suggest clauses, and to have this discussion as a continual part of being a citizen of the country.
On nearly every other aspect of civilisation we have been first to change, for example the Industrial revolution, but in this respect we can gain from taking all the best bits from the existing constitutions, and really create something worthwhile.
However, though I would applaud and even forgive Blair if he started this discussion
eek
, I suspect that he won't as Turkeys don't vote for xmas, and he is too much of a parliamentarian. Git!
