Answer
The United Kingdom's entry into the European Economic Community (EEC), a precursor to the European Union, was enabled by Georges Pompidou. Pompidou, who served as the President of France from 1969 to 1974, played a pivotal role in facilitating negotiations and fostering diplomatic relations between the UK and the EEC. His support and influence were instrumental in paving the way for the UK's ultimate accession to the EEC in 1973.
