There is evidence at least 20 prominent paedophiles - including former MPs and government ministers - abused children for "decades", a former child protection manager has told the BBC.

Peter McKelvie, whose claims initially led to a 2012 police inquiry, said a "powerful elite" of paedophiles had escaped investigation for years, but there was now a chance of justice for the victims.
