Trade unionist Paul Embery has delivered a stark warning about Labour's vulnerability to Reform UK, telling GB News that "the taboo has been broken" regarding working-class voters switching allegiances.

Speaking about the party's precarious position, Embery highlighted that Labour's share among the occupational working class remained static at 33 per cent between the 2019 and 2024 elections, despite their landslide victory.

Speaking to Martin Daubney on GB News he explained: "The reality is, parts of the Labour Party are grasping at straws.

"There's this Red Wall caucus now in Parliament of Labour MPs. The Reform wolf is at the door.

"Unless Labour does what it really needs to do in terms of getting growth in the economy, getting immigration numbers down, and getting NHS waiting lists down.

"Then the old tribal loyalties, where people in those communities voted Labour regardless, are disintegrating.

"The taboo has been broken. People will vote for Reform, as they did in Runcorn, and they'll have no compunction about doing it again if they think Reform is the party that's going to represent their priorities.

"Labour has a massive battle on its hands to hold off that Reform threat."

GB News host Martin Daubney reacted to Embery's analysis by giving him a 'chef's kiss', adding he "absolutely nailed it".

Recent YouGov polling from May shows Reform UK in first place nationally, eight percentage points ahead of Labour and ten ahead of the Conservatives.

The survey reveals that only 60 per cent of Labour's 2024 voters remain loyal, with 15 per cent intending to vote for Reform, whilst 12 per cent have switched to the Liberal Democrats and 9 per cent to the Greens.

Among working-class voters, 38 per cent now support Reform compared to just 19 per cent backing Labour, marking a dramatic shift from generations past when this demographic formed Labour's bedrock.

The data also shows Reform drawing 27 per cent of former Conservative voters and commanding 91 per cent loyalty among its own supporters.

Labour's recent victory in the Hamilton, Larkhall and Stonehouse by-election offers little comfort despite defeating the SNP on a 7.4 per cent swing.

Reform UK surged to third place with 26.1 per cent of the vote, just behind Labour's 31.6 per cent and the SNP's 29.4 per cent.

The result prompted Reform's Deputy Leader Richard Tice to tell BBC Radio 4: "We've come from nowhere to being in a three-way marginal, and we're within 750 votes of winning that by-election."

Political scientist John Curtice observed that "Reform are making the political weather north of the border, as indeed they are south of the border."
