For almost a century, governments in the United Kingdom have attempted to find a way to undertake a comprehensive reform of the House of Lords, which is the upper house of the Parliament of the United Kingdom. This process was started by the Parliament Act 1911 introduced by the then Liberal Government which stated:
When the Labour Party came to power in the 1997 general election, it had in its manifesto the promise to reform the House of Lords:On 7 November 2001 the government undertook a public consultation. and numerous debates in Parliament and the media. However, no consensus on the future of the upper chamber emerged.
All three of the main parties promised to take action on Lords reform in the 2010 general election, and following it the Coalition Agreement included a promise "to bring forward proposals for a wholly or mainly elected upperchamber on the basis of proportional representation".
