From 1982 to 1990, following the Falklands War, there were no diplomatic relations between the UK and Argentina. There was no Ambassador, but the embassy building remained open, as the British Interest Section of the Swiss Embassy, rather than as the British Embassy. The Argentine Embassy in London came under the Brazilian flag during the same period. Diplomatic relations were restored in 1990.
