Wiltshire (European Parliament constituency)

Prior to its uniform adoption of proportional representation in 1999, the United Kingdom used first-past-the-post for the European 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. The constituency of Wiltshire was one of them.

The constituency consisted of the Westminster Parliament constituencies of Devizes, Newbury, North Wiltshire, Salisbury, Swindon, Wantage, Westbury.

The constituency was represented for the whole of its existence by Caroline Jackson. At the 1994 European election, there were boundary changes. Most of Wiltshire then became part of the new Wiltshire North and Bath constituency, which again elected Caroline Jackson.
