The north Londoner is one of many signatories on the campaign to urge the government to stop the proposed changes to Personal Independence Payments (Pip).
Deaf and disabled people are asking the prime minister in an open letter to adopt a different approach, after the Department for Work and Pensions announced what it called the biggest shake up to "rebalance" the welfare system.

More than 140 celebrities including activists Liz Carr and Jack Thorne have signed the open letter, which was released on Tuesday.
Comedian, actor and author, Samantha Baines, is an advocate for hearing loss and has signed the letter.
