The British Sign Language Bill will give BSL legal recognition in England, Wales and Scotland and will impose on the government a duty to issue new guidance and publish reports on what each department is doing to promote or facilitate the use of BSL.

The private member’s bill was backed by West Lancashire Labour MP Rosie Cooper as well as Conservative peer Lord Holmes of Richmond.

Lord Holmes detailed the difference the bill would make, saying: “As a result of this bill, BSL signers will be able to have such appointments and all communications with the state in an inclusive manner, rather than having to rely on parents, spouses, siblings or children to communicate such news.”

He said it was “enabling, empowering… including BSL signers, benefitting us all”.

Conservative frontbencher Baroness Scott of Bybrook said: “It is indeed an historic day for our deaf community. The Government is committed to supporting all people with a disability, including deaf people, to lead fulfilled and independent lives.”

Chief executive of the National Deaf Children’s Society, Susan Daniels, said: “Thousands of deaf children use British Sign Language and this will be a day of celebration for all of them. It’s also a powerful symbol of recognition for the deaf community and a big step towards real equality.

“What’s important now is that we maintain the momentum and keep shining a light on the issues deaf children face, because their fight doesn’t end here.”
