LONDON — Nigel Farage’s Reform UK has welcomed an offer from MI5 to help political parties vet their election candidates as hostile states try to infiltrate British democracy.

Last month MI5 — Britain’s domestic intelligence agency — said it would help political parties with candidate checks for potential foreign interference risks.

A Reform spokesman told POLITICO the party would be “very interested” in taking up the offer, if it “comes to fruition.”

Ken McCallum, the director general of MI5, made the offer at a cross-party briefing with U.K. political parties last month, alongside Security Minister Dan Jarvis, three people with knowledge of the meeting told POLITICO.

The offer from McCallum is part of a wider effort by the U.K. government and security services to shore up British democracy amid a wave of espionage activity from hostile states.

In the past six months, several foreign and U.K.-born citizens have been arrested on suspicion of working for Iran, Russia and China.

Earlier this month three former Labour officials, including the husband of a sitting Labour MP and former candidate for North Wales police and crime commissioner, were arrested by counter-terrorism police on suspicion of spying for China.

Last year, the former Reform UK leader in Wales Nathan Gill was jailed for accepting bribes to make pro-Russian statements while he was a member of the EU parliament for Reform’s precursor Brexit Party.

Britain’s political parties have no standardized system for vetting those who want to become MPs. Each party has its own internal, and in some cases, external processes for probity checks.

Reform leader Nigel Farage in 2024 blamed a “reputable vetting company” for oversights in helping sift its candidates ahead of the general election after one praised Hitler and backed Russia’s war in Ukraine. He apologized, adding: “We have been stitched up politically and that’s given us problems.”

MI5’s role in vetting is limited to its own staff and certain levels of security clearance for specific government and official roles in Whitehall. Its offer to candidates is expected to be limited to helping parties assess foreign interference risks, rather than any official security clearance.

POLITICO asked the six main Westminster parties if they will take MI5 up on its offer to assist in their vetting processes. The ruling Labour Party, the Conservatives, the Greens and the Liberal Democrats all declined to comment. The Scottish National Party did not immediately respond to a request for comment.

The offer from Ken McCallum is part of a wider effort by the U.K. government and security services to shore up British democracy amid a wave of espionage activity from hostile states.

A Reform UK spokesman said: “If this offer comes to fruition, we would be very interested in taking the MI5 up on it. 

“We must do all we can to stamp out foreign interference in our politics. We have seen just last week with the Labour China spy scandal just how deeply embedded this issue is.”

The government unveiled its Counter Political Interference and Espionage Action Plan last November. It includes an elections bill, which is currently making its way through parliament. An independent review into financial interference in U.K. democracy is examining the use of cryptocurrency. Ministers are also considering bringing in proscription-like powers to disrupt proxies and state-backed terror groups as part of the plan.

A Government spokesperson said: “The Security Minister is coordinating an action plan to ensure we’re doing all we can to safeguard our democracy, including working directly with political parties to help them detect and deter interference and espionage.

“We’re also strengthening rules on political funding, rolling out security advice for election candidates, and working with professional networking sites and think tanks to make them a more hostile operating environment for foreign agents.”
