Caroline Lucas will argue later today that Ed Miliband should argue for "a genuinely proportional electoral system" and support Lucas's amendment that on the Parliamentary Voting System and Constituencies Bill which would include a proportional voting system on the ballot paper in the forthcoming referendum.
She will be speaking at a Compass meeting at Labour party conference (29 Sept 2010, 1230pm, Peter House, Oxford Street, M1 5AN).
Lucas will say that: "Without an electoral system that gives people the freedom to vote for what they believe in, and see those beliefs turned into political representation, the kind of politics that we want will never come.
"I think that the time has come for Labour to make that compromise. It is the right thing to do, and it is also a potential insurance against experiencing the kind of presidential, even dictatorial leadership that we have all suffered from in recent years."
