CAMPAIGNERS demanded reform today after a damning report laid bare shocking conditions facing migrant workers propping up Britain’s crumbling care system.

Unison surveyed more than 3,000 people who came to Britain on health and care worker visas to tackle shortages in the sector.

It found that nearly a quarter had paid fees to an employer or an intermediary upfront in return for a job — with dozens handing over more than £20,000.
