Analysis

The Labour Party remained the largest party in Wales and won an even larger majority of seats after gaining three seats from the Conservatives. Its 48.9% of the vote and total of 771,354 popular votes were its best in Wales since 1997.^[3]

The Conservative Party, who entered the campaign with high hopes of making gains, saw its representation reduced back to the levels it won in the 2010 general election.^[4]

Plaid Cymru won back Ceredigion after the constituency's 12 years in Liberal Democrat hands, and brought its tally up to four seats, which was its best result showing since 2001 and one of its joint best in history.^[5][6]

Plaid Cymru's gain in Ceredigion and the Liberal Democrats' failure to make gains elsewhere meant that this was the first time in Welsh electoral history where there were no Liberal or Liberal Democrat MPs elected to represent a Welsh constituency in a Westminster Parliamentary election.^[7][8]
