The Green Party has long campaigned for radical parliamentary reform, to give people more influence over the decisions that affect them at every level of government.

We want more powers for local councils, not for unelected quangos.

We want a Bill of Rights, a written constitution, an elected second chamber. The power for local people to recall their MP. Measures to promote the involvement of more women and members of ethnic minorities. We want fixed term parliaments.

Above all, we need proportional representation. David Cameron rejects this idea out of hand, despite claiming he wants to revitalise politics by devolving power.

The first-past-the-post electoral system almost always results in a minority government - a government that most people have voted against rather than for. It’s time the mother of parliaments caught up with the rest of Europe and more truly reflected the diversity of political opinion in the country as a whole.
