The Green Party is taking heavyweight legal advice into a meeting tomorrow which will discuss who will pay for the note-taker its deaf MP, Mojo Mathers, needs to follow proceedings in Parliament.
Speaker of the House Lockwood Smith has been criticised for his decision not to grant funding for Ms Mathers, but he has said he does not have the authority to approve it.
The matter will be discussed by the Parliamentary Service Commission - made up of senior MPs from all parties - tomorrow night.
A spokeswoman for Dr Smith - who has been paying for the service from his parliamentary budget while the matter is being debated - said he had "some options to offer".
However, the commission only provides advice to Dr Smith, and the final decision rests with him.
