 Murray was knighted in 1962 (, 1950), when he was appointed British Ambassador to Greece.He held this post until 1967 and the right wing coup of the Greek Army Colonels which led to the formation of the Greek military junta of 1967-1974.He appears to have been frustrated with the passivity of the British government's actions both in the lead up to the coup of which there was some intelligence foreknowledge, and its ineffectual response.
