This is a table of the former European Parliament constituencies in the United Kingdom, listing the number of Members of the European Parliament each elected at each European Parliamentary election. The United Kingdom left the European Union on 31 January 2020. As a result, these constituencies no longer exist. With the exception of Gibraltar's inclusion in South West England, the constituencies otherwise corresponded with the NUTS 1 regions of the United Kingdom, though the naming differed slightly to distinguish them from other European constituencies. *
