Mayall twice publicly involved himself in political campaigns. In 2002 he dressed up as Adolf Hitler for a cinema advertisement opposing the United Kingdom abolishing its national currency the Pound sterling in favour of the Euro, as a part of its membership of the European Union. In the United Kingdom Alternative Vote Referendum of 2011 he appeared in a television broadcast for the 'No' campaign in character as Alan B'Stard to oppose the adoption of an alternative non-proportional electoral system for Westminster Parliamentary elections.
