Eliasson, 53, a lawyer, is currently the director-general of the national social insurance agency, Försäkringskassan, where he has overseen changes to cut down administration and make it easier for parents to claim compensation for sick children. He was previously in charge of the Migration Board.
He will start his new job in January and told news agency TT that the offer came out of the blue. He said that it was not part of his immediate plans to leave the insurance agency where he enjoys the work, but it was too good to turn down. "It feels like an irresistible mission," he said.
Home Affairs minister Anders Ygeman announced the appointment at a press conference Thursday.
Dan Eliasson's main task will be to oversee a massive reorganisation of the police force with the 21 police authorities set to disappear next year, to be replaced by one large, central authority. It is the biggest structural change in the police force since 1965, and the planned changes have not been without criticism, attacking, for example, the speed of the enforced change.
Current National Police Commissioner Bengt Svenson will stay on until March, when his contract expires.
