November 2002 parliamentary electoral results in the southeastern province of Siirt were cancelled and by-elections called for, following evidence of irregularities in the November poll. In the new elections, held 9 March 2003, Recep Tayyip Erdogan, the leader of Turkey's ruling Justice and Development Party (AKP), won a seat in parliament. The victory made it possible for Erdogan to replace his close associate Abdullah Gul as prime minister.
Finals results show the AKP won 84.7 per cent of the vote.
