Game of Thrones actor Kit Harington has called on the government to fund six years' back pay for overnight carers.
Revenue & Customs has ruled care workers sleeping overnight to provide safety and reassurance should get the national minimum wage for all hours.
But Harington fears people such as his cousin Laurent, who has Down's syndrome and autism, could suffer as a result.
The government said it would "ensure that action taken to protect workers is fair and proportionate".
But Harington said: "If the charities can't pay this bill, then people are going to be left without the care they need."
