Antigua and Barbuda's High Commission in London anchors the twin-island nation's diplomatic presence in the United Kingdom, maintaining bilateral relations focused on tourism promotion, Commonwealth cooperation, and educational exchange. The mission serves as a vital link for the significant Antiguan and Barbudan diaspora in Britain, many of whom migrated during the Windrush era and subsequent decades. London's role as a major tourism source market makes this diplomatic post particularly important - British visitors consistently rank among the top European travelers to Antigua's renowned beaches and annual Sailing Week. The High Commission facilitates visa processing for UK residents traveling to the Caribbean nation, supports trade relationships in sectors including offshore financial services and light manufacturing, and coordinates on shared priorities within the Commonwealth framework including climate resilience for Small Island Developing States.
