Reform UK, led by Nigel Farage, is predicted to make significant gains in Labour’s leave-voting strongholds following the end of Sir Keir Starmer’s initial popularity surge, a recent opinion poll claims.

The Prime Minister’s support has seen somewhat of a decline just eight weeks after his triumphant victory, positioning Farage’s party as a serious contender for Labour in many constituencies.

The latest BMG opinion poll shows Labour’s support at 30 per cent, a drop from 34 per cent on July 4.

Several seats could witness a backlash from pensioners against Labour due to Starmer’s decision to means-test Winter Fuel Payments.

In Suffolk Coastal, where 30 per cent of constituents are over 65, Labour won by less than 1,000 votes on July 4.

But the poll reveals that Reform UK’s gains would be modest.

They could, however, pose a threat to Starmer in the so-called Red Wall, some have predicted.

A survey placing Reform UK at 19 per cent suggests that the populist party could potentially seize the likes of Amber Valley, Dudley, Llanelli, Montgomeryshire & Glyndwr and Sittingbourne & Sheppey.

Labour could face a loss of 63 seats at the next General Election if the polling is accurate, with Election Polling’s swingometer indicating that the Tories would take 55.

The Liberal Democrats, led by Sir Ed Davey and currently polling at 11 per cent, could also lose four seats as the Tories reclaim some Blue Wall seats.

Candidates supporting Palestine could see an increase of six members, bringing their total to 11.

Despite only gaining three additional seats in this projection, Reform UK came second in 98 seats on July 4.

Labour held 89 of the 98 seats where the populist party finished second.

Reform UK is expected to strategise ahead of its conference later this month.
