In line with the broader British policy of decolonisation on 26 July 1965 an agreement was signed on behalf of His Majesty the Sultan by Ibrahim Nasir Rannabandeyri Kilegefan, Prime Minister, and on behalf of Her Majesty The Queen by Sir Michael Walker, British Ambassador designate to the Maldive Islands, which ended the British responsibility for the defence and external affairs of the Maldives. The islands thus achieved full political independence, with the ceremony taking place at the British High Commissioner's Residence in Colombo. After this, the sultanate continued for another three years under Muhammad Fareed Didi, who declared himself King rather than Sultan.
