The MP who alleged that the late parliamentarian Sir Cyril Smith was a paedophile said he is prepared to name a second, living, politician who he believes is guilty of child abuse.

On 1 July, Simon Danczuk, Labour MP for Rochdale, is scheduled to give evidence to the Home Affairs Select Committee concerning allegations that Smith abused children at the Elm Guest House in south-west London in the 1970s and the 1980s.

An MP on the committee has confirmed to the Independent on Sunday that Danczuk will be asked about other visitors to the guest house when he appears before them.

"If asked any question, I will feel obliged to answer that question," Danczuk told the paper.

Danczuk has previously claimed that an "influential" politician who is still in parliament, was a visitor at the guest house, where a paedophile ring that included Smith allegedly groomed and abused boys.

"I'm confident there are questions to answer. I base that on quite extensive conversations I've had with the police," Danczuk said.

Police launched an investigation into the alleged child abuse ring at Elm Guest House after claims by Labour MP Tom Watson.

Earlier this month Conservative MP for Richmond Zac Goldsmith called for the UK Home Secretary Theresa May to launch a parliamentary inquiry into the conclusions of an investigation into child abuse at Knowl View School in Rochdale, where Smith was a governor.

The committee will ask Danczuk and campaigner Matthew Baker what they believe happened at Elm Guest House.

Protected by parliamentary privilege, they will be able to give evidence without fear of litigation.

Danczuk told the Independent that if asked, he will also name another living politican who he believes is implicated in a separate child abuse scandal.

So far, police have made no charges in connection with the investigation.

Officers are also investigating claims that a VIP paedophile ring abused boys at Grafton Close Children's Home in Richmond, south-west London.
