Thousands of sick or disabled people have died after being assessed to find out whether they were fit to work, the Commons was told.

MPs attacked Atos, the firm contracted to conduct work capability assessment (WCA) tests for the Government.

Former Labour minister Michael Meacher accused the firm of "ruthlessly" pressurising the sick and disabled into work.

Opening a Commons debate, he said 1300 people had died after being placed in the "work-related activity group", for those too ill to be in a job but expected to take steps towards an eventual return to employment.

An Atos Healthcare spokeswoman said: "We know that this can be a difficult process for people and we do all we can to make sure the service we provide is as professional and compassionate as possible."
