Rochdale's current MP says there are still questions to answer over whether there was a cover-up. Simon Danczuk says Cyril Smith's victims have been let down by the Crown Prosecution Service and the Director of Public Prosecutions.
Greater Manchester Police have said the dead Liberal MP Sir Cyril Smith should have been charged with physically and sexually abusing young boys:
"We are now in a position to say that on three separate occasions, files were passed to first the DPP and then the CPS containing details of abuse committed by Smith, but on each occasion no prosecution was pursued.
Having now reviewed those decisions, we believe that if the same evidence was presented to the CPS today there would have been a very realistic prospect that Smith would have been charged with a number of indecent assaults, and that the case would have been brought to trial.
Clearly that is a bold statement to make but it is absolutely important for those victims who were abused by Smith that we publicly acknowledge the suffering they endured.
Although, Smith cannot be charged or convicted posthumously, from the overwhelming evidence we have it is right and proper we should publicly recognise that young boys were sexually and physically abused and we will offer them as much support as they need should they wish to speak to us.
Greater Manchester Police, which has assumed the investigation into allegations of sexual abuse made against the dead Liberal MP Sir Cyril Smith has said: "The Force is now publicly acknowledging that young boys were victims of physical and sexual abuse committed by Smith."
Any fresh abuse allegations against Sir Cyril Smith "will be thoroughly investigated," Greater Manchester Police said.
There has been a lot of speculation in the media about whether Greater Manchester Police investigated allegations of sexual abuse involving the late Sir Cyril Smith in the 1980s and 1990s.
We are examining our records to see what involvement Greater Manchester Police may have had. However, we need to be clear that some of these allegations are up to 30-years-old and predate our computerised records, so it will take some time to establish what, if any, the Force's involvement was.
What I can say with clarity is that any fresh complaints that are made will be thoroughly investigated and we will continue to work with our colleagues at Lancashire Police to provide support to any victims who come forward.
