On 22 May 2005, after the SPD lost to the Christian Democratic Union (CDU) in North Rhine-Westphalia, Gerhard Schröder announced he would call federal elections "as soon as possible". A motion of confidence was subsequently defeated in the Bundestag on 1 July 2005 by 151 to 296 (with 148 abstaining), after Schröder urged members not to vote for his government in order to trigger new elections. In response, a grouping of left-wing SPD dissidents and the neo-communist Party of Democratic Socialism agreed to run on a joint ticket in the general election, with Schröder's rival Oskar Lafontaine leading the new group.
