Former Reform MP Rupert Lowe will not be charged after facing allegations of making threats, the Crown Prosecution Service (CPS) has said.

Malcolm McHaffie, head of the Crown Prosecution Service’s Special Crime Division, said after considering a number of witness statements they have concluded that there is “insufficient evidence to provide a realistic prospect of conviction”.

He added: “The Crown Prosecution Service’s function is not to decide whether a person is guilty of a criminal offence, but to make fair, independent, and objective assessments about whether it is appropriate to present charges for a criminal court to consider.

“Based on the careful consideration of this evidence, we have decided that our legal test for a criminal prosecution has not been met.”

Mr Lowe was suspended by Reform UK and reported to police following allegations that the MP threatened violence towards party chairman Zia Yusuf.

He always denied wrongdoing and claimed he was the victim of a witch hunt after speaking out against party leader Nigel Farage in the media.

In a lengthy statement following the CPS’s decision, the Great Yarmouth MP said he was referred to the police in “a sinister attempt to weaponise the criminal justice system against me – putting not just my political future, but my liberty at risk”.

He said this was “all because I dared to raise constructive criticisms of Nigel Farage, stood firm on deporting illegal migrants, and pushed for Reform to be run democratically – not as a vehicle to stroke one man’s ego”.

Reform responded “with a brutal smear campaign”, he said, claiming figures in the party briefed journalists he had dementia.

Farage ‘a coward and a viper’

Mr Lowe said: “I am ashamed to have shared a parliamentary platform with them. Ashamed to have trusted them. Ashamed to have called them friends. Farage is no leader – he is a coward and a viper. I feel deeply embarrassed that I ever thought he was the man to lead.

“It’s my view that the police process was weaponised to silence a party colleague who raised reasonable concerns.

“If Farage were ever to control the vast power of the British state, I believe he would not hesitate to do to his adversaries what they have tried to do to me. With real power, I fear he would wield that immense responsibility to crush dissent – as he has done time and again over the years.

“Smearing my innocent staff in a pathetic attempt to attack me was disgusting, alongside briefings to journalists from senior Reform figures suggesting I had dementia – the lowest, vilest tactics I have seen in my 67 years. They are not fit to lead. They are not fit to be MPs.”

Mr Lowe went onto say that “for the good of our country, Nigel Farage must never be prime minister”.

In a hint at his political future he added: “When the time soon comes, we will work together to advance a political movement that is credible, professional, decent, democratic and honest. There will, very soon, be an alternative to the rotten leadership of Reform.

“You’ll be hearing a lot more from me, very soon.”

Sky News has contacted Reform UK for comment.

The row poses danger for a party that has its sights on entering government at the next election after a meteoric rise in the polls.

It broke out in March after Mr Lowe gave an interview to the Daily Mail in which he said it was “too early to know” if Mr Farage will become prime minister and warned Reform remains a “protest party led by the Messiah” under the Clacton MP.

Soon after, Reform UK announced it had referred him to police and suspended him, alleging he made “verbal threats” against chairman Zia Yousaf.

The party also claimed it had received complaints from two female employees about bullying in his constituency offices, which he also denied.

Mr Lowe was one of the five Reform MPs elected to parliament in July and now sits as an independent.

He previously sat as the chairman of Southampton Football Club before entering politics.

During Mr Farage’s online falling out with Elon Musk in January, in which the world’s richest man said Reform needed a new leader, Mr Lowe drew praise from Mr Musk.
