Luke Hamill helped launch Scope's election manifesto, which demands that the next government introduces measures to bring greater equality for disabled people.
Hamill plays Dean McVerry in ITV's long-running drama The Bill, and has used a wheelchair since he was involved in a car accident at the age of 18.
Scope's manifesto calls on the future government to effect equality through measures such as guaranteeing all disabled people control over their day-to-day lives and disabled children the right to mainstream education.
Hamill said: "It's vital that the next government takes Scope's manifesto seriously. Education, transport and employment are crucial components of a civilised society - ours is currently 'disablist'."
The launch of the manifesto is part of Scope's ongoing Time to Get Equal campaign.

The author, who is also the patron of the MS Society Scotland, said: "Having seen my mother suffer with MS, I cannot imagine what it would have been like if I had been 12 and trying to look after her. Yet this is the situation that 175,000 young people in the UK face."
