[5][6] He completed his highly successful third term on December 31, 2023, having played a widely recognized role in guiding the work of the Permanent Council in the peaceful transition of government in Guatemala on 14 January 2024.

[9] He served twice as Antigua's High Commissioner to the United Kingdom (1983–1987, 1996–2004)[10] as well as ambassador to the World Trade Organization (WTO) (1997–2004).

[27] Sanders' campaign for the post was torpedoed the day before the election by a story in British newspaper The Daily Telegraph that had been touted to other media but rejected by them.

The story was based on an eleven-year old, unsubstantiated allegation made in an unpublished report by the political party then in office in Antigua and Barbuda.

[34] The committee presented its report in July 2021[35] and all of its recommendations, particularly to maintain Commonwealth Studies, were accepted by the University Council.

[33] From January to April 2016, he served a highly praised period as Chair of the Permanent Council of the 34-member Organization of American States.

[37] The Permanent Council is the decision-making body responsible for the affairs of the OAS between meetings of foreign ministers of the member countries.

[43][44] He held several Special Meetings of the Permanent Council on challenges being experienced in the Americas such as climate change, irregular migration, guns, gangs, and violence, in addition to other issues of democracy and security confronting the Member States of the OAS, particularly Guatemala.

[50] The transition process was contentious due to efforts by Guatemala’s Public Ministry to overturn the results of the first and second round of elections held on June 25, 2023 and August 20, 2023, respectively.

[47] Along with the Secretary General, Sanders held discussions with President Giammattei, senior judges of Guatemala’s Constitutional Court and Vice President-Elect Karin Herrera.

[58] Sanders participated in meetings with judges of Guatemala’s Constitutional Court, the Human Rights Ombudsman, the president of the Supreme Court of Justice, the Minister of Foreign Affairs, Mario Búcaro, President-elect Bernardo Arévalo, members of the 48 Cantones and other indigenous and ancestral authorities, and members of the Coordinating Committee of Agricultural, Commercial, Industrial, and Financial Associations (CACIF).

[58] Sanders’ role in helping to guide Guatemala to a peaceful transition of government was praised by key players in Guatemala, including the foreign minister, Mario Búcaro Flores who, on 21 December 2023, expressed “heartfelt appreciation” for Sanders’ “exceptional leadership as Chair of the Permanent Council”, saying “your guidance has been instrumental in addressing critical issues and advancing the wellbeing of our citizens”.

[65][66]  Subsequently, together with Sierra Leonese lawyer, Abass Bundu, as technical assistance from the Commonwealth Secretariat, he participated in meetings with all the Heads of Government and Opposition leaders in preparation for the formulation of the Treaty, establishing the Organization of Eastern Caribbean States.

[69] He left the Foreign Service formally in 1987 but continued pro bono work for the government of Antigua and Barbuda before returning, once again, as High Commissioner to London from 1996 to 2004.

[10] He was also bestowed with the dignity of Commandeur dans l’Ordre des Palmes Academiques in April 2002 by the Republic of France.

[80] He has written several chapters and Forewords in books, as well as articles in academic journals, on the politics and economies of the Caribbean and the Commonwealth.
