Comprising the 40 parliamentary constituencies in Wales. At the 1997 general election Labour won 34 seats, Plaid Cymru 4 and the Liberal Democrats 2.
Wales, like Scotland, tends to produce results which disproportionally favour Labour, albeit that the party regularly receives in excess of 50% of the vote here. The Conservatives, by contrast, got no seats in 1997 despite polling almost 20% of the vote.
Plaid Cymru, with its support concentrated in the Welsh-speaking north and west, picked up 1 in 10 of both the votes and the seats, whereas the Liberal Democrats won just 2 seats with a larger share of the vote.
The proportional system to be used for the European Parliament elections will correct the worst of these anomalies. However, as Wales is only electing 5 MEPs, the second smallest regional allocation, each individual party will require a share of the vote well into double figures to secure a seat.
