1979: British ambassador assassinated in Holland
British ambassador in Holland Sir Richard Sykes was shot dead outside of his Dutch home in March 1979.
Two gunmen opened fire on Sir Richard and his Dutch footman as they left his residence at The Hague to make the five-minute car journey to the embassy.
Security came under scrutiny after the killing as there was no permanent guard on the ambassador's residence.
This report was originally broadcast on 22 March 1979.
