 After major disputes inside the FPÖ between Haider and vice-chancellor Susanne Riess-Passer (the so-called "Knittelfeld Putsch"), the ÖVP broke the coalition in 2002 and called for re-elections.Riess-Passer left the FPÖ, and the former Minister of Social Services, Herbert Haupt, was appointed as new leader.In a brilliant marketing move, Chancellor Wolfgang Schüssel convinced the then very popular Minister of Finance Karl-Heinz Grasser to change from the FPÖ to the ÖVP.
