The policy documents outline benefit cuts of £5bn, including for 800,000 of those on Personal Independence Payments and an additional 150,000 carers.

Liberal Democrat Work and Pensions spokesperson, Steve Darling, who himself is registered blind, said: ‘For the Government to now put forward these major changes in a way that many can't even access is nothing short of a disgrace.'

The Liberal Democrats said the failure to publish the accessible documents could put the Government at risk of breaking its own regulations.

Darling said the Government was in ‘real danger of losing its moral compass' and called on ministers to immediately publish the accessible versions of their Green Paper and impact assessment.

A DWP spokesperson said: ‘We want to hear from a wide range of people during the consultation period and are committed to putting the views and voices of disabled people at the heart of everything we do which is why we will be publishing the accessible versions and launching the 12-week consultation shortly.

‘We have set out a sweeping package of reforms to health and disability benefits that genuinely support people back into work, while putting the welfare system on a more sustainable footing so that the safety net is always there to protect those who need it most.'
