New Ministry for Public Administration was formed, with Davorin Mlakar appointed minister.
Former Minister of Science, Education and Sports Dragan Primorac, who also stepped down the day after Sanader's resignation, was replaced by Radovan Fuchs only days before the Kosor cabinet was officially announced.
Although initially retained as Minister of Economy, Labour and Entrepreneurship, Damir Polančec resigned three months later on 30 October 2009 and was replaced by Đuro Popijač in November.
Bianca Matković, who was appointed Minister without portfolio in Kosor's cabinet, was relieved from her post in March 2010. Since no one was appointed to replace her, her post was also terminated.
In May 2010 Ivan Šimonović was appointed United Nations Assistant Secretary-General for Human Rights. Following the appointment, Šimonović was replaced by Dražen Bošnjaković on 7 July 2010. Bošnjaković previously held the post of state secretary with the Ministry of Justice.
