The Conservative leader David Cameron says that a Tory government would cut the number of MPs by nearly 10%, from 646 to 585, saving about £15 million a year.
He's also threatening a 5% reduction in ministerial salaries and - possibly the unkindest cut of all for many at Westminster - the abolition of subsidised food and drink in Parliament's restaurants and bars.
And at their October 2009 party conference, the Conservatives announced that, if elected, they would reform outdated parliamentary procedures, describing the Commons and the Lords as "an analogue Parliament in a digital world".
The shadow Commons leader, Sir George Young, promised to end the automatic guillotining of government bills, which cuts short debate even if key issues haven't been discussed.
And he said the chairmen of influential select committees should be given the chance to launch their reports in the Commons chamber itself - and that MPs should be given more say over the Commons agenda.
