The reason for his resignation is attributed to the actions of Krista Kiuru, the Minister of Education and Science.
Kiuru is part of a ministerial working group on public administration and regional development led by Henna Virkkunen, the Minister of Public Administration and Local Government.
It is reported the Kiuru had strongly advocated for the interests of her home region of Satakunta in the preparation of the draft law.
Miettinen was appointed by Virkkunen in 2012. According to Virkkunen the state allocates money to municipalities based on an outdated data.
