Constitutional Convention Bill

The Constitutional Convention Bill was a bill introduced in the British House of Commons by Graham Allen MP on 22 July 2015 and never went past the first reading. The bill was also introduced in the House of Lords by Lord Purvis of Tweed and reached committee stage.
Aims.
Under the bill, the following would be established:
Origins.
The Constitutional Convention Bill was first mentioned of in the Labour Party Manifesto for the 2015 General Election. The driving factor behind the Bill was the fact that the Labour Party had been pushing constitutional reform, as well as the left-wing movement in general (see the House of Lords Reform Bill), and that there had not been a single constitutional document in the United Kingdom - rather a series of laws and agreements promulgated over centuries, like the Magna Carta and the Act of Settlement (1701). This is a similar attempt to compile relevant legislation, comparable to when the Brown Ministry was working on the Equality Act, which was given royal assent in 2010.
Composition.
The Constitutional Convention would be composed of representatives of the nations and regions, the local authorities, and registered political parties. There was a quota of 50% percent of convention members that must not be in any employment that could be considered political.
