Flintshire was a parliamentary constituency in North-East Wales which generally returned one Member of Parliament (MP) to the House of Commons, latterly that of the Parliament of the United Kingdom, from 1542 until it was abolished for the 1950 general election. Boundaries From its creation in 1542 until 1918, the constituency consisted of the historic county of Flintshire in north-east Wales. The seat should not be confused with the borough constituency of Flint or that of Flint Boroughs, which together existed from the 16th century until 1918. In 1889 an administrative county of Flintshire was created. This formed the basis of the constituency which existed from 1918 until 1950, when the county was split between East and West divisions.
