From the BBC:
Liberal Democrat leader Nick Clegg is calling for the number of MPs in the House of Commons to be cut by 150.
This would save taxpayers millions of pounds and cut political parties’ need to raise cash from big donors, he says.
In a speech setting out his proposals for re-building trust in politics he will also call for a shake-up in party funding and a new electoral system.
He also proposes people be asked, when voting at elections, if they want to donate £3 to a party of their choice.
Mr Clegg is expected to say there should be a £25,000 cap on donations to political parties and a £10m limit on annual spending by political parties.
