Miguel Piernavieja del Pozo

Miguel Piernavieja del Pozo (21 May 1916 – 8 June 1983)[1] was a Spanish spy for Nazi Germany, operating in Britain during the Second World War.

He was quickly spotted by the Security Services (MI5) who gave him the codename Pogo and used one of their double-agents to feed him disinformation which was relayed to the Germans.

Born in Santa Cruz de Tenerife on 21 May 1916,[1] Piernavieja was a Falangist who had worked for Francisco Franco during the Spanish Civil War.

[8][9] Williams posed as an ardent Welsh nationalist and Piernavieja gave him £3900 (a sum more than 10x the average annual wage[10]) in a talcum-powder tin and asked him to obtain information on the Welsh nationalist movement and on factories making munitions in the west of England.

[2] Piernavieja was awarded the Iron Cross for his military service in the Division Azul on the Eastern Front.
