Just reading the BBC article on some proposed reform ideas, and for the life of me I can't see why they all shouldn't be innacted immediately.
Suggestions are;
Proportional representation - Ending what critics see as the inherently unfair "first-past-the-post" system of electing MPs
• Fixed term parliaments - Ending the advantage to the ruling party of choosing the polling date
• A written constitution - Setting out voters' rights and limiting the power of government
• A fully elected second chamber - Ending the power of patronage and expelling the few remaining hereditary peers
• Curbing the power of the whips - Freeing MPs to to vote with their conscience more often rather than following the party line
• Fixed terms for MPs - So they do not become too cosy and complacent in their roles
• Boosting the power of select committees - Electing the chairmen rather than having them chosen by the whips and handing them greater investigatory powers
