Sir Mark Allen (b.1950) is a British businessman and former spy. He worked for the British Foreign Service for 30 years, rising to Director of Counter-Terrorism in MI6, before retiring in 2004. He has since acted as special advisor for BP and for the Monitor Group. Sir Mark’s involvement with Libyan politics – from oil reserves to allegations of support for torture – have brought him under scrutiny since the downfall of Muammar al-Gaddafi in 2011.
