London - Another BBC national treasure has emerged from the woodwork whose decades-long paedo rampage was whitewashed over much like Jimmy Savile's.
Named only as 'Uncle Dick' in veteran war correspondent John Simpson's 1999 memoir the perv was once outed as BBC children's presenter 'Uncle Mac' - the nickname of Derek McCulloch OBE [1897-1967].
Notches on his pervy belt include presenting BBC Radio's Children's Favourites and Children's Hour and for playing the part of 'Larry the Lamb' in Toytown.
His stellar broadcasting career eventually bombed following what some called a 'whispering campaign' pointing the finger at his extracurricular activities with youngsters.
An avalanche of innuendo and scurrilous gossip eventually climaxed in 1964 with official questions being asked in Parliament under the guise of concerns about 'disastrous audience ratings' of his Saturday morning show.
MPs had demanded to know if there was an altogether more sinister interpretation of McCulloch's comments about privileged use of 'posh' new lavatories at the newly opened Broadcasting House.
BBC staff had been briefed that those earning more than £1,000 per annum would have their own private keys to the exclusive facilities.
The move effectively segregated ordinary 'pleb' broadcasters to using the HQ's standard urinals.
McCulloch was quoted as saying the issue of 'them and us' bogs was largely irrelevant because 'we will still all have to use the same sewers.'
Attempts to prosecute him failed a number of times after BBC bosses testified that a 'failing heart' and other physical bad health issues should rule out any prosecution as a serial perv.
An official blue plaque at the UK seaside town of Broadstairs commemorates McCulloch's broadcasting heights.
