The Green Party's campaign battle bus was back in Norwich today as part of a national tour to rally support for the party.

The Routemaster bus, which runs on recycled cooking oil, was a familiar sight during last year's European election campaign.

Yesterday it stopped off outside the Theatre Royal before heading to West Earlham, Vauxhall Street, Tuckswood and the University of East Anglia.
