Ms Badenoch and the billionaire Trump advisor jumped on a decision by Labour not to back a new probe into allegations of abuse in Oldham.

 The X owner used the platform to allege that the Prime Minister allowed rape gangs to ‘ exploit young girls without facing justice’ when he was England and Wales’ top prosecutor.

Ms Badenoch joined him and Reform UK figures including Nigel Farage by leaned into the row on social media, tweeting: ‘The time is long overdue for a full national inquiry into the rape gangs scandal.

Last January a report found young girls were ‘left at the mercy’ of paedophile grooming gangs for years in Rochdale because of failings by senior police and council bosses.

The damning 173-page review covers 2004 to 2013 and sets out multiple failed investigations by Greater Manchester Police (GMP) and apparent local authority indifference to the plight of hundreds of youngsters, mainly white girls from poor backgrounds, all identified as potential victims of abuse in Rochdale by Asian men.

Successive police operations were launched, but these were insufficiently resourced to match the scale of the widespread organised exploitation within the area.

The report follows reports by the same authors on grooming in Manchester and Oldham, which found authorities had again failed children, leaving them in the clutches of paedophiles.

The Independent Inquiry into Child Sex Abuse, which published its final report in 2022, described the sexual abuse of children as an ‘epidemic that leaves tens of thousands of victims in its poisonous wake’.

Led by Professor Alexis Jay, the inquiry looked into abuse by organised groups following multiple convictions of sexual offences against children across the UK between 2010-2014, including in Rotherham, Cornwall, Derbyshire, Rochdale and Bristol.

In November last year, Professor Jay said she felt ‘frustrated’ that none of the probe’s 20 recommendations had been implemented more than two years after its conclusion.

In a letter to the council, Ms Phillips said she believes it is ‘for Oldham Council alone to decide to commission an inquiry into child sexual exploitation locally, rather than for the Government to intervene’.

An Oldham Council spokesman said: ‘Survivors sit at the heart of our work to end child sexual exploitation. Whatever happens in terms of future inquiries, we have promised them that their wishes will be paramount, and we will not renege on that pledge.’

Mr Musk’s  attack came as he lined up to support Robinson, the diminutive far-right agitator whose real name is Stephen Yaxley-Lennon.

The English Defence league co-founder was sentenced to 18 months in prison in October after admitting 10 beaches of a High Court injunction barring him from repeating libellous allegations against a Syrian refugee.

However, Mr Farage, whose party has been linked to a $100million donated from Mr Musk, replied: ‘Talk is cheap. The Conservatives had 14 years in government to launch an inquiry. The establishment has failed the victims of grooming gangs on every level.’

He also alleged that Safeguarding Minister Jess Phillips was refusing to investigate the gangs because it would lead back to the PM’s time as director of public prosecutions between 2008 and 2013.

However, his attack came as he lined up to support Robinson, the diminutive far-right agitator whose real name is Stephen Yaxley-Lennon.

During the unrest over the summer, billionaire Musk engaged with posts by Robinson, suggesting that civil war in the UK was ‘inevitable’.

He also retweeted a fake Daily Telegraph headline suggesting rioters would be sent to detention camps in the Falkland Islands.

Writing on X last night Mr Musk said: ‘In the UK, serious crimes such as rape require the Crown Prosecution Service’s approval for the police to charge suspects.

‘Who was the head of the CPS when rape gangs were allowed to exploit young girls without facing justice? Keir Starmer, 2008 -2013.’

He added: ‘Who is the boss of Jess Phillips right now? Keir Stamer (sic). The real reason she’s refusing to investigate the rape gangs is that it would obviously lead to the blaming of Keir Stamer (sic) (head of the CPS at the time).’

However, Sir Keir started the original investigation into gangs in Rochdale in 2012, the year before he left office as DPP.

He also tweeted ‘free Tommy Robinson’ and retweeted a follower who claimed Robinson was a ‘political prisoner’, a viewpoint held by many of the incarcerated Englishman’s supporters.

Mr Musk’s support for Robinson could cause some unhappiness in the Reform Party.

Reports have suggested that he is preparing to hand it a war chest of up to $100million (£79million).

But party leader Nigel Farage has previously distanced himself from Mr Robinson, who was once a political adviser to Gerard batten, Mr Farage’s successor as leader of Ukip.

It comes weeks after Mr Musk, a close advisor to incoming US president Donald Trump, voiced his support for the German far-right party Alternative für Deutschland (AfD).

Sir keir was director of public prosecutions between 2008 and 2013.

Robinson was sentenced to 18 months in prison in October after admitting 10 beaches of a High Court injunction barring him from repeating libellous allegations against a Syrian refugee.

 A Home Office study published in 2020 that found child sexual abuse gangs are most commonly made up of white men.

Mr Musk has spent considerable time attacking Sir Keir since Labour came to power.

Last week he attacked the party over its economic plans for the UK.

Responding to a story about Scottish politicians urging him to invest in a Tesla gigafactory, the billionaire posted on X: ‘Very few companies will be willing to invest in the UK with the current administration.’

Downing Street insisted Sir Keir was running an ‘unashamedly’ pro-growth government, but refused to criticise Mr Musk directly.

Asked about Mr Musk’s view about the government being anti-business, the PM’s spokesman said: ‘We look forward to working with President-elect Trump and indeed his team to progress the UK-US special relationship, and particularly the UK-US trade and investment relationship, which supports hundreds of thousands, if not millions, of jobs both sides of the Atlantic, and tens of billion pounds of investment and trade.’

He added: ‘I’m not going to kind of get into commentary on individual comments, but if you look at what’s happened since the election, you’ve seen the £63 billion of additional investment from the Investment Summit.

‘You’ve seen the Government respond to some of the businesses’ key concerns in the UK, which is lack of stability, and the Government’s brought back that stability, both politically and economically.’

Downing Street declined to comment on Mr Musk’s latest comments today.
