You are able to read evidence the Work & Pensions Select committee has received so far here.

More evidence will be being received, as there are still two more deadlines:

18th July – for people needing support in submitting written evidence,
1st August – for people submitting evidence in BSL.

There is some advice on how to ensure your evidence is considered on DeafAtW. It is really important you read this before writing/submitting further evidence. Read the update here.
