In the run-up to the general election of 2006, Reinfeldt, as leader of the Moderate Party, participated in the creation of the Alliance for Sweden. It united the centre-right in a coalition of the Moderate Party, the Centre Party, the Liberal People's Party and the Christian Democrats. Reinfeldt is said to have been instrumental in uniting the four parties, which previously were known for being notoriously divided, in order to present a powerful alternative to the Social Democrats. The parties presented a joint election manifesto for the alliance.
