A six-week-old political party blasted through to win across Monmouthshire and Wales in an election many had decided was a de-facto second European referendum.

The Brexit Party, whose sole policy is to ensure Great Britain leaves the European Union, scooped one-third of the vote in Monmouthshire, whilst the pro-EU Liberal Democrats enjoyed a mini-resurgence, coming second in Monmouthshire with 20.4 per cent of the vote.

The Conservatives bore the brunt of voter anger and apathy, with the party of national government slumping to its worst nation showing since the 1800s.

In Monmouthshire, the results trickled in as follows: Brexit Party: 33 per cent, Lib Dems: 20.4 per cent, Conservative Party: 11.4 per cent, Plaid Cymru: 10.8 per cent. The Green Party gathered up 9.3 per cent of the vote, whilst the new Change UK defied its early polling of 18 per cent to sink to just 3.8 per cent. Meanwhile, the party Nigel Farage deserted after its shift toward anti-Islam policies, Ukip, got 2.7 per cent of the vote. Analysts set turnout at 42 per cent of all eligible voters.

In Blaenau Gwent, the Brexit Party surged to 37.4 per cent, followed by Labour on 23 per cent, whilst Plaid Cymru settled on 12.9 per cent of the vote. The nationally resurgent Lib Dems managed 6.6, per cent, whilst the Conservatives scraped 3 per cent of the vote on a turnout of just over 30 per cent.

The Brexit Party won an unprecedented triumph for a six-week-old political party in Wales and across the UK on Sunday night in the European Parliament election as it stormed to a comfortable first-place.

Nigel Farage’s party dominated in Wales, winning 32.5 per cent of the vote, two of the nation’s four MEPs and coming top in 19 of 22 Welsh council areas.

The Brexit Party’s success came at the stark expense of both Labour and the Conservatives. Both suffered historic failures across Wales as the vote totals were announced.

The Welsh nationalists, Plaid Cymru, bested Labour for in second place in Wales, winning one European Parliament seat with 19.6 per cent of the vote, sending shockwaves amongst Welsh Labour’s hierarchy. Adam Price, leader of Plaid, declared that Wales was a “Remain nation”.

Labour, with 15.3 per cent of the vote, only narrowly beat the Liberal Democrats to take the fourth and final Welsh European Parliament seat. The Conservatives, with 6.5 per cent of the vote, only squeaked ahead of the Green Party. It was the Tories’ worst result across the UK since 1832.

Nigel Farage, whose party topped the vote across the UK, however said that the Brexit Party’s success hinged on one element: “We voted to leave and we haven’t.”

He then warned the Conservative party that the UK must leave the European Union on October 31 this year, or his Brexit Party will contest all 650 seats at a general election in which polls indicate huge losses for both Conservative and Labour incumbents.

The result in Wales was a significant change on 2014 when Labour won 28.15 per cent of the vote and Ukip 27.55 per cent. Wales’s MEPs are now Nathan Lee Gill (Brexit Party), James Wells (Brexit Party), Jill Evans (Plaid Cymru) and Jacqueline Jones (Labour).
