THE United Kingdom has announced the appointment of Joseph Guy Fisher MBE as the new British High Commissioner to the Republic of Guyana, with concurrent accreditation as His Majesty’s Non-Resident Ambassador to the Republic of Suriname and UK Ambassador to CARICOM.
Fisher will assume duties in April 2026, succeeding Jane Miller OBE, who is set to retire from the Diplomatic Service.
The appointment places Fisher at the centre of the UK’s diplomatic engagement with Guyana and the wider Caribbean Community at a time of deepening economic, security and development partnerships.
A seasoned diplomat, Mr Fisher brings a strong background in national security, foreign policy coordination and international development. Most recently, he served as Private Secretary to the National Security Adviser at 10 Downing Street between 2024 and 2025.
His portfolio also includes senior advisory responsibilities within the Foreign, Commonwealth and Development Office (FCDO), where he served as Deputy Principal Private Secretary to the Foreign Secretary from 2022 to 2024.
Fisher’s career reflects extensive experience across multilateral diplomacy and complex political environments. He previously worked within the UK Cabinet Office’s National Security Secretariat, rising from Team Leader to Deputy Head of Department between 2020 and 2022.
His overseas postings include diplomatic assignments in Myanmar, where he served as Acting Deputy Head of Mission in Yangon in 2020 and earlier as Second Secretary (Political/Press) from 2011 to 2014. He also held a key liaison role with the Office of Daw Aung San Suu Kyi between 2014 and 2017, focusing on international development coordination.
Earlier in his career, Fisher served in Afghanistan’s Helmand Province as Second Secretary (Political) with a Provincial Reconstruction Team, underscoring his experience in conflict and post-conflict environments.
He joined the UK’s Foreign and Commonwealth Office in 2007 and has since held a range of roles spanning EU affairs, ASEAN coordination, and information technology policy.
His professional training includes completion of the Higher Command and Staff Course at the UK Defence Academy in 2024, as well as Myanmar language training at the School of Oriental and African Studies.
Fisher’s appointment signals a continuation of the UK’s engagement with Guyana, particularly as the country advances its position in the global energy market and deepens regional integration through CARICOM.
Further details on his arrival and official accreditation are expected in the coming weeks.
