A demonstration will take place in Truro today to protest against the Government policy on assessing people’s fitness for work.
Campaigners protesting against the work capability assessments say the system is unfair and has harmed the health of some people who have been assessed.
Atos Healthcare, an occupational health service provider, holds a number of government contracts and interviews people who want to claim benefits on behalf of the Department for Work and Pensions (DWP).
Police have closed parts of Pydar Street in advance of the demonstration.
Campaigner Michelle Kent will be taking a wreath to the event as she said people have lost their lives due to the assessments.
She said: "What people have to go through is appalling and extremely humiliating.
"Atos makes millions from the poorest and we are also asking that the work compatibility assessments are carried out by people's own GPs and not a health practitioner that's nowhere near qualified to carry them out."
The demonstration will be held outside the Truro Assessment Centre in Pydar Street at 10am.
