Reform UK has come under pressure to provide evidence its candidates at the general election were all real people after doubts were raised about a series of hopefuls who stood without providing any photos, biographies or contact details. Reform insists every one of its 609 candidates on 4 July were real, while accepting that some were in effect “paper candidates” who did no campaigning, and were there simply to help increase the party’s vote share. However, after seeing details about the apparently complete lack of information about some candidates, who the Guardian is not naming, the Liberal Democrats called on Reform to provide details about them. A Liberal Democrat source said: “This doesn’t sound right and Reform should come clean with evidence. We need Reform to show who they are. People need to have faith in the democratic process.” A series of candidates listed on the Nigel Farage-led party’s election website only show their name and the constituency they stood in, without any information about them, or contact details beyond a generic regional email address. Many of these people have no visible online presence, and did not appear to do any campaigning. Photographs of the electoral counts for some of the relevant constituencies show that the Reform candidate was the only person not to attend. Under electoral rules, the only details that need to be given about the candidate is their full name and the constituency where they live. They must all have an agent, and be nominated by 10 local voters. With some of the Reform candidates, it is not clear if they are listed on the electoral register for the area where they are standing – which in a few cases is hundreds of miles from the constituency in question. One person with the same name and location of a candidate denied it was them. While there is no evidence any of the candidates are fake, if that turned out to be true, it would be a serious electoral offence. Reform was keen to win as big a share of the national vote as possible, which is helped by a full slate of candidates. Some of the seemingly invisible candidates won several thousand votes. A Reform source said: “All our candidates are categorically real. Given the rush, a few are just paper candidates and didn’t campaign. Some people began as paper candidates but then did campaign, and one of these – James McMurdock in South Basildon and East Thurrock – ended up winning his seat.” The Guardian has also learned that one Reform candidate suspected of being fake, in part because his official election photo looked AI-generated, is a real person. The suspicions about Mark Matlock, who won 1,758 votes in Clapham and Brixton Hill in south London, were compounded when he did not show for the election count, with sceptics also pointing to an apparent lack of any photographs of him campaigning. However, Matlock insisted that he did exist, and there was a reason for the curious-looking election picture: “The image is me. Stupidly I had to get it altered to change my tie and suit as I couldn’t get to a photographer on time.” He showed the Guardian a copy of the original image, which was changed to make his tie a Reform light blue. Matlock, who lives in the Cotswolds, said he did undertake a leaflet drop, adding that he understood the rush to get candidates in place: “The election caught us all on the hop and Rishi Sunak knew that. But we still managed to fill most of the seats with candidates, even if not all of them lived there, and it all contributed to our vote share.” The Clapham and Brixton Hill candidate said he missed the election count because he had pneumonia. Separately, it has emerged that Reform raised the most out of all political parties during the fourth week of the election campaign, bringing in almost £600,000 – of which a third was from the party’s new donor, Zia Yusuf. Yusuf, a Muslim businessman who spoke at a recent Reform rally, is the founder of a luxury concierge company called Velocity Black, and gave Nigel Farage’s party £200,000. Other donors to Reform include £125,000 from Jeremy Hosking, a businessman who recently backed Laurence Fox’s Reclaim party, and the anti-vax former Tory MP Andrew Bridgen.
