The Marquess of Lothian asked Her Majesty’s Government “when they last discussed policy towards Iran and the Joint Comprehensive Plan of Action with the government of the United States.”

Lord Ahmad of Wimbledon, Minister of State for Foreign and Commonwealth Office responded “We have been clear with the US about our determination to preserve the Joint Comprehensive Plan of Action at all levels. The Foreign Secretary spoke to Secretary of State Mike Pompeo on 5 March regarding Iran, and the British Ambassador in Tehran was in Washington DC meeting a range of representatives in the US Administration during the week of 11 March.”
