Mr Farage’s belief that allowing Commonwealth citizens to vote “undermines national sovereignty” and leads to elections being fought over international rather than domestic issues is behind the plan to remove their right to vote in national polls, Reform UK has said.

Asked if he was worried that the policy could be seen as an effort to cut out voters unlikely to support his party, Nigel Farage said that many other “normal” countries already do this.

He said: “I do believe for national elections they should be they should be voted on by British voters only, absolutely.

“Otherwise, we get a really, very, very perverse influence on our politics, where people are voting more about Gaza than they are about Gorton.”

Reform UK Treasury spokesman Robert Jenrick said many other countries including the US and Japan already limit voting rights to citizens.

Mr Farage added: “We just want to be a normal country and normal countries protect their borders, protect their democratic systems, know what works and what doesn’t.”

Reform also wants to restrict postal voting.

Currently, anyone eligible to vote in UK elections can choose to do so by post but under Reform UK’s plans this would be limited to the elderly, disabled, serving armed forces personnel and those working overseas during an election.

Mr Farage warned on Monday of the “mass harvesting” of postal ballots.

“I don’t trust the postal voting system. I don’t trust the electoral register,” he said.

The Reform UK leader has complained about postal voting in the past, including when Ukip lost the Oldham West and Royton by-election in 2015 and when his Brexit Party lost the Peterborough by-election in 2019.

Reform UK MP Richard Tice questioned the validity of postal ballots when his party’s candidate lost the Rochdale by-election in 2024, stressing the result should act as a “serious wake-up call” to the electorate and those in power.

In none of those cases was postal voting fraud ever proved and none resulted in any convictions.

Reform has also asked police to investigate allegations of election fraud after reports of “family voting” – an illegal practice where two voters use one polling booth and potentially direct each other on voting.

Election observer group Democracy Volunteers warned it had witnessed “concerningly high levels” of family voting in Gorton and Denton.

Commenting on Nigel Farage’s plans, a Green Party spokesman said: “This is dangerous, racist nonsense from a party who were well beaten, seeking to delegitimise the election, Donald Trump-style.

“In a democracy, everyone’s vote is equal and we attracted voters from across all communities, in all areas, including from those who said they were originally going to vote Reform.

“Farage has no idea who did and didn’t vote for him.

“And, as he said, he always knew they were going to lose. ‘If you don’t like the results of an election, change the electorate’ is the refrain of sore losers and anti-democrats through the ages.”
