Activists campaigning for Rupert Lowe's Restore party joined neo-Nazis at a summit of white supremacists, The Mail on Sunday can reveal. 

Supporters canvassing for votes in this week's knife-edge Makerfield by-election were among those attending the far-Right event, which called for a white-only Europe. 

The news comes as Mr Lowe told this newspaper that he didn't care if his party split the Right-wing vote in the constituency and allowed Labour leadership hopeful Andy Burnham to sweep into the Commons. 

Polls put Labour just five points ahead of Reform UK in Makerfield, with Restore Britain on eight per cent – more than enough to deny Mr Burnham victory if they switched their votes to Nigel Farage's party instead. 

But Mr Lowe was defiant about the prospect of helping Mr Burnham towards No 10 and shifting the government even further to the Left, telling this newspaper that Restore's actions did not 'make a jot of difference'. 

Among those campaigning for Restore in the constituency on Saturday was Callum Barker, a 'hardened neo-Nazi' who was at the extremist Remigration Summit in Portugal two weeks ago.  

Remigration is a far-Right concept referring to ethnic cleansing via the mass deportation of non-white minority populations. 

It was conceived as a response to the 'Great Replacement' conspiracy theory which asserts that global elites – often Jews – are systematically trying to replace white people with immigrants. 

Barker has posted images that reference '1488', shorthand for a 14-word white nationalist slogan and '88', which stands for 'Heil Hitler' – H being the eighth letter of the alphabet.

Lucy White, another Restore activist, spoke at the conference and interviewed prominent American white supremacist Jared Taylor, whom she described as 'a true pioneer, a true legend'. 

Also addressing a panel there was a Restore activist who uses the name 'Angloid' online – but has been identified as 19-year-old Lorcan Barker. All three have been pictured with Mr Lowe.

Barker recently posted a video claiming that Reform UK had 'gone woke' after Mr Farage stated that the mass deportation of hundreds of thousands of immigrants was not a realistic possibility.

Steve Laws, another vocal backer of Restore who has been described as a neo-fascist and ethnic cleansing extremist, was also at the event. 

Laws – who on Saturday posted online about the success of Restore's Makerfield campaign – said last week: 'We all know Jews should be deported. I don't care where they go. But they can't stay here.'

A Restore Britain spokesman last night described the revelations about the summit as 'totally irrelevant' and a 'hit piece'.

Polling experts believe Restore could be the deciding factor in swinging Thursday's contest in Burnham's favour. 

Luke Tryl of the More In Common pollsters said this weekend: 'Andy Burnham is on track for Makerfield win – thanks to Restore Britain.'

But asked whether he would mind costing Farage the seat, Mr Lowe said: 'I don't think it makes any difference whether Andy Burnham wins. 

The people in power are the Labour Party. Most of them are completely incompetent, they haven't done anything and they know they are going to lose their seats at the next election.'

Meanwhile Mr Farage urged voters on the Right to 'come together' to ensure Labour did not take the seat. He said: 'I understand voters want radical change – I do too.

'Now is the time to come together and stop Andy Burnham and Labour, this is our only opportunity. Reform is the only party promising wholesale change from the establishment status quo that can win.'

Mr Lowe was elected as a Reform MP in the 2024 general election, but left the party amid public disputes with Mr Farage, setting up the rival party last year. 

He denied that personal animosity with Mr Farage was spurring him on to split the vote, adding: 'Nigel doesn't want to lead.

'He's managed opposition, that's all. I can't understand why he did what he did to me. It was a surprise. I was driving the party's support. I'm a team player.'

A number of his party's supporters have been linked to extremists. Last month the Mail revealed Restore had reinstated Dundee member James Munro, who had been expelled over pictures of him holding a neo-fascist flag and making a Nazi salute. 

Munro had said: 'This picture was from about ten years ago. It was a different time. There were no legitimate avenues for young men in nationalism, so back then you had to get dirty.'

Last month's Remigration Summit in Figueira da Foz, Portugal was organised by Martin Sellner, an Austrian activist banned from the UK. 

He has admitted he was previously a neo-Nazi who, aged 17, placed swastika stickers on a synagogue – although he has tried to distance himself from his past. 

Sellner has praised Restore Britain, saying: 'It is crucial for Restore to establish a sharp profile and criticise Farage and Reform from the Right'.

Taylor – the extremist praised by Lucy White – once wrote: 'When blacks are left entirely to their own devices, Western civilisation – any kind of civilisation – disappears.'

The summit was also attended by Dries Van Langenhove, a Belgian extremist who in 2024 was sentenced to a year in jail – later suspended – for his role in operating chatrooms filled with neo-Nazi memes and praise for Adolf Hitler.

He was also convicted of denying the Holocaust, with a judge saying he 'revelled in Nazi ideas that cause much suffering'.

If Mr Burnham wins in Makerfield, Sir Keir Starmer is expected to face moves to topple him within hours. 

Although the Prime Minister has insisted he will stay to fight off a challenge, Labour MPs are plotting to force him to set a timetable for his departure.

If Mr Burnham gets into Downing Street he has made clear he wants to pursue an agenda more Left-wing than Sir Keir's. 

Ed Miliband is tipped to be his Chancellor and those close to Mr Burnham have already indicated sweeping tax rises would be on his agenda.
