Blue Peter Special Assignment was a factual BBC TV series broadcast in the 1970s and early 1980s, the first spin-off from the long running BBC series Blue Peter. It ran regularly from 1973 until 1981, usually at weekends on BBC1, and was heavily promoted on Blue Peter itself. The concept for the series was developed after Valerie Singleton had made a successful documentary 'special' with HRH Princess Anne when she had visited Kenya in 1971.
