Parish councils are the smallest unit of local government.
They put the town hall on people's doorsteps. They are more accessible and more accountable than any other part of local government. More importantly, they are the most participatory and, therefore, the most democratic institutions in the British political system. Campaigns by the Green Party for urban parish councils would generate a great deal of publicity. Greens could publish a monthly newsletter in each parish to keep people informed about what was happening and to outline policies they would like to implement.
