Atos has been heavily criticised after refusing to disclose its profits from carrying out benefit assessments on behalf of the Department for Work and Pensions (DWP).
The private firm withdrew from its contract to carry out Employment and Support Allowance (ESA) assessments following concerns over accuracy and fairness.
However, Atos were still awarded a contract to carry out Personal Independence Payments (PIP) assessments.
ATOS boss David Haley told the Scottish Welfare Reform Committee in June that he would come clean about how much money the firm makes. However, just two months later Atos has U-turned and refused to disclose this information.
PIP provides crucial financial and practical support to disabled people between the ages of 16 to 64. The new benefit is replacing Disability Living Allowance as part of government’s wide-spread changes to the welfare system.
Joan McAlpine MSP said: “At the Welfare Reform Committee in June ATOS boss David Haley agreed to disclose the profits that they expect to make from their Personal Independence Payment (PIP) contract.
“It is simply unacceptable that they are now trying to wriggle out of that commitment.
“They had to be dragged kicking and screaming to the Scottish Parliament in the first place – and now it is clear they were just fobbing us off with promises that they had no intention of keeping.
“ATOS are happy enough to do the UK Government’s dirty work by carrying out assessments that can lead to sanctions on welfare payments for disabled people – and they must now come clean on how much money they are making from this contract.
“The Tory Government ministers hide from answering questions Scotland’s Parliament – but the sooner the organ grinder Iain Duncan Smith comes here to explain his decisions, which make life so difficult for so many vulnerable and hardworking Scots, the better.”
