On November 3, 2026, the Prime Minister of the United Kingdom met with Prime Minister Gaston Brown of Antigua and Barbuda. The meeting took place on the margins of the Commonwealth Heads of Government Summit (CHOGM), which was held in St. John's, the capital of Antigua and Barbuda. The Commonwealth Summit traditionally brings together leaders of participating states of the organization to discuss bilateral and multilateral cooperation, economic development, climate agenda, and other current issues. The details of the negotiations between the two prime ministers were not officially disclosed; however, such meetings within the framework of similar summits are typically devoted to strengthening diplomatic ties, trade and investment issues, as well as regional and global challenges, including climate change, which is particularly relevant for Caribbean island nations.
