It was suggested in June 2006 by Conservative leader David Cameron that, if he joined the Conservative Party and put himself forward, Ferrari could win the ballot to be the party's candidate for Mayor of London. Ferrari indicated, however, that he would not stand, as he "did not want to leave the listeners" and joked that he "couldn't take the pay cut". Later, he began to see merit in the idea and discussed what policies he might introduce should he become Mayor: amongst these were re-introducing the AEC Routemaster buses (with various modifications so that they would conform to disability and environmental laws) and scrapping the Mercedes-Benz "Bendy Buses" and, more controversially, putting a large levy on trainers in the run-up to the 2012 Olympic Games and doubling income tax on Human Rights lawyers. Ferrari later indicated that he would not stand as the Conservative candidate, a role that was taken by Boris Johnson.
