People with 'invisible' disabilities could soon have greater access to blue badges under new government plans.

The proposals, introduced by Transport Minister Jesse Norman, would help remove barriers to travel for people with conditions such as dementia and autism, allowing them better access to work, shops and amenities.

Around 2.4million disabled people in England have a blue badge which allows them to park on roads without charge, and 75 per cent of blue badge holders say they would go out less often if they didn't have one.

Mr Norman said: "Blue badges give people with disabilities the freedom to get jobs, see friends or go to the shops with as much ease as possible.

"We want to try to extend this to people with invisible disabilities, so they can enjoy the freedom to get out and about, where and when they want."

The changes could see healthcare professionals who are better placed to identify if mental health causes mobility issues, carry out assessments to determine if a blue badge should be given.

It is hoped that the plans, which would herald the most significant changes since the blue badge was introduced in 1970, will create parity between physical and mental health.

Sarah Lambert, head of policy at the National Autistic Society, said: "The National Autistic Society welcomes this government proposal. It could mean that many more autistic people will qualify for a blue badge, which can be a lifeline."

The consultation will last eight weeks.
