Stoiber had ambitions to run again for the chancellorship, but Merkel secured the nomination, and in November 2005 she won the general election. He was slated to join Merkel's first grand coalition cabinet as Economics minister. However, on 1 November 2005, he announced his decision to stay in Bavaria, due to personnel changes on the SPD side of the coalition (Franz Müntefering resigned as SPD chairman) and an unsatisfactory apportionment of competences between himself and designated Science minister Annette Schavan. Stoiber also resigned his seat in the 16th Bundestag, being a member from 18 October to 8 November.
