Secretary of State for Foreign and Commonwealth Affairs
Despite this, in 2008 the House of Lords in "R v Secretary of State for Foreign and Commonwealth Affairs, ex parte Bancoult (No 2)" held that the plenary power exists to the extent that even legislation removing all inhabitants from a territory is valid; this was later confirmed in the 2016 UK Supreme Court case "R (on the application of Bancoult (No 2)) v Secretary of State for Foreign and Commonwealth Affairs".
