Erixon has also been active as a politician with the Swedish Centre Party, where he was a leading critic of former party leader Olof Johansson. Erixon expressed strong objections towards Johansson's close co-operation with the Social Democrats during the period 1995–98, which he argued outright prohibited the emergence of a serious centre-right alternative to the Social Democratic administration at the time. While Erixon is no longer a member of the Centre Party, he did support and vote for candidates of the party both in the 2006– and 2010 general elections. During the 2002 election he had however toured with the libertarian Free List party ("Fria Listan"), which gained little support and was eventually dissolved.
