British Foreign Secretary Dominic Raab announced last week that Richard Moore would take over as director of the Secret Intelligence Service (MI6), Britain’s equivalent of the United States Central Intelligence Agency.

Moore, 57, will be replacing Sir Alex Younger, who has served as MI6 chief since 2014. British media reported that Moore served as an undercover MI6 officer for years before being appointed ambassador in 2014. Moore was born in Libya to British parents and studied at the Universities of Oxford and Harvard. He then joined MI6 and served under official cover in Vietnam, Pakistan, Malaysia and Turkey, where his cover was as the British embassy’s press attaché, from 1990 to 1992. He then held a number of posts in Britain’s Foreign and Commonwealth Office, including his current position, Director General for Political Affairs. Before that he served as British Ambassador to Turkey, where he lived from 2014 to 2017.

Following the announcement of Moore’s appointment as MI6 director, it emerged in the British press that his grandfather, Jack Buckley, was a volunteer in the Irish Republican Army (IRA) in Cork, Ireland. Buckley reportedly joined the separatist IRA in 1916 and served in its ranks until 1922. He was eventually honored by Sinn Fein —the IRA’s political wing— with a medal for his service in the war against the British, which resulted in the independence of most of Ireland and the creation of the Free Irish State. It is today commemorated across Ireland as the Irish War of Independence.

Moore discussed his grandfather’s membership in the IRA during his stint as ambassador to Turkey. He told a Turkish newspaper that he was of Irish origin and that his grandfather had “fought against the British government in the separatist Irish Republican Army”. He was making the point that, over time, national differences between peoples can be smoothed out given the right conditions, and made a comparison between his family’s experience and the conflict between Turkey and the Kurds.

Moore is scheduled to assume his new post in the fall. He is expected to remain as director of MI6 until 2025.
