Reform UK risks losing momentum as it heads into its annual conference in Birmingham, after a summer that failed to deliver the national breakthrough Nigel Farage sought. The party entered the long parliamentary recess expecting to press advantage with provocative messaging and council-level initiatives, but a string of tactical errors and fresh scrutiny of its funding have constrained its reach.

Farage provoked attention by forcing a byelection in Clacton, a move designed to blunt questions about an undeclared £5m donation from megadonor Christopher Harborne. The result was a comfortable win for Farage, but the campaign tied him to one corner of the country for six weeks and paused a parliamentary standards probe only temporarily. Press activity by Farage slowed as a result, reducing the national profile his lieutenants struggle to generate.

Internal strains also surfaced. Home affairs spokesperson Zia Yusuf was reprimanded by Farage after branding former Conservative defence secretary Ben Wallace a “traitor”. The party also suspended prominent defector Tim Montgomerie, signalling friction between high-profile recruits and the leadership. Such rows add to questions over Reform’s centralised structure and whether Farage’s dominance is simultaneously an asset and a constraint.

Polling offers a stark picture. A More in Common survey put Reform at 23%, four percentage points behind Labour and its weakest showing in 18 months. Ipsos polling has Labour on 28% and Reform on 25%. Ipsos also found 65% of the public do not believe Farage is ready to be prime minister, while nearly three quarters supported continuing the standards investigation before the Clacton contest concluded.

On the ground the party faces competition on its right flank. Rupert Lowe’s Restore Britain took 10% in a Dover district council by-election, a result that helped the Greens narrowly beat Reform in an area where Reform had performed strongly last year. Reform sources point to a package of new policies and stepped-up council action, citing recent moves by bodies such as Kent to limit immigration in local areas, and say the conference will unveil further headlines and a larger business engagement programme.

As delegates assemble, the immediate test is tactical recovery and message discipline. The party must show it can translate council wins and policy launches into wider electoral appeal, while the revived standards inquiry and splintering on the right will demand attention. If Reform cannot broaden its support beyond core voters, the winter political calendar will offer few easy opportunities to regain the run of the national conversation.
