IT company Atos has confirmed it is seeking to end its government contract to assess whether benefits claimants are fit to work.
Staff carrying out work capability assessments for Atos have received death threats online and in person, according to the Financial Times.
In a statement, Atos pledged to carry on undertaking the tests until a new company was in a position to take over.
The government said that standards at Atos had declined unacceptably.
