The independent inquiry into child sexual abuse in Rochdale has been urged to look deeper at what the national political parties knew about Cyril Smith and when they knew it.
Rochdale's former Liberal MP will be the focus of the UK inquiry when it begins hearing evidence next month.
In London today, Richard Scorer, the solicitor who represents nine survivors of Rochdale abuse, called on the inquiry to ask the Liberal Democrat and Labour parties to tell them all they know.
We have contacted the Labour and Liberal Democrat parties at national level. The Labour Party told us they are "co-operating fully with the inquiry." We are awaiting for the response of the Liberal Democrats.

We've contacted the Labour and Liberal Democrat parties at national level.
The Labour Party told us they are, in their words, co-operating fully with the inquiry.
We're still waiting for a response from the Liberal Democrats.
