Dominic Cummings is reportedly helping Elon Musk to attack the UK senior Government sources have claimed.
Mr Cummings, who was Boris Johnson’s Chief Adviser at No.10, is believed to be in contact with the richest man in the world via WhatsApp.
Sources have told the Mail on Sunday that Mr Cummings is also advising the Tesla owner on how to slash trillions of dollars from US government spending.
The South African-born billionaire has spent much of the past week using his social media platform X, attacking the Prime Minister over his opposition to another national inquiry into grooming gangs.
In other posts he has expressed support for Reform UK, but called for its leader Nigel Farage to step aside, and asked his 212 million followers whether the US should “liberate” the UK from its “tyrannical government”.
Sources told the Mail suspicions Mr Musk and Mr Cummings were plotting together were raised by the tech entrepreneur’s use of terms such as “two-tier Kier” and the UK timing of his incendiary posts.
They claimed Mr Cummings and Mr Musk were swapping ideas via a WhatsApp group shared with an unidentified US businessman.
A Musk ally said: “It is 100% true they are talking. It is not just Elon – Dom is in constant contact with major Silicon Valley figures.”
The claims come after a poll showed half the British public believe Mr Musk is having a negative impact on UK politics.
Some 53% of people told pollster Opinium they thought Mr Musk was having a negative impact on British politics, compared to just 12% who thought he was having a positive one.
On his comments about grooming gangs in particular, 47% said they thought Mr Musk was being “unhelpful” compared to 26% who thought the opposite.
Reform UK voters were similarly unmoved by Mr Musk’s claim Mr Farage should stand down as leader, with 71% saying the Clacton MP was the best leader they could have now.
Adam Drummond, head of political and social research at Opinium, said a “lack of enthusiasm about a foreign billionaire involving himself in British politics” was “one area of agreement” among the public.
Earlier this week, Mr Farage insisted he could repair relations with the incoming adviser to US President-elect Donald Trump, but said Mr Musk’s support was not “crucial” and it was more important to maintain his long-standing opposition to jailed far-right activist Tommy Robinson.
The split between Mr Farage and Mr Musk came after the billionaire expressed strong support for Robinson, whose real name is Stephen Yaxley-Lennon.
Meanwhile, Mr Cummings is planning a new StartUp Party to smash the traditional Westminster model.
The party aims to challenge the Westminster status quo ahead of the next election, with policies including taking Britain out of the European Convention on Human Rights, embracing artificial intelligence and shaking up Whitehall.
Mr Cummings and Mr Musk have been approached for comment.
