South Wales East (European Parliament constituency)

South Wales East was a European Parliament constituency covering southeastern Wales, including Gwent and parts of Mid Glamorgan.

Prior to its uniform adoption of proportional representation in 1999, the United Kingdom used the first-past-the-post system for the European Parliament elections in England, Scotland and Wales. The European Parliament constituencies used under that system were smaller than the later regional constituencies, and only had one Member of the European Parliament each.

South Wales East replaced the similarly named South East Wales in 1984, and became part of the much larger Wales constituency in 1999.
