UK Cabinet ministers' personal phone numbers found online, including Defence Secretary's

Full text

LONDON — The personal mobile phone numbers of three U.K. Cabinet ministers — including Defense Secretary Wes Streeting — have been found published online alongside their names.

The discovery comes after POLITICO reported that Prime Minister Andy Burnham fell victim to a texting scam — engaging with messages from someone impersonating Susie Wiles, Donald Trump’s White House chief of staff, before becoming suspicious the contact was illegitimate and ending the conversation.

After checking through a list of Cabinet members, POLITICO found three published on the web, for Streeting, Justice Secretary Alex Norris and Northern Ireland Secretary Chris Bryant. POLITICO is not pointing to where the numbers can be found to avoid further risking security.

All three ministers declined to comment on the record. The reference to Streeting’s number online has since been deleted, and officials are working to remove the other two.

Ministers are given secure government devices to conduct business for their briefs, in particular for high-risk roles like defense, and are expected to use those for non-personal comms.

A government spokesperson said: “The government has robust procedures in place to ensure the security of sensitive information.”

But Prerana Joshi, research fellow at the Royal United Services Institute (RUSI) think tank, said that having direct numbers for Cabinet ministers in the public domain is a risk, warning that numbers could be spoofed and used to call others at a time when the U.K. is “in a high threat situation” globally.

“In any civil space, if your number is exposed, a whole host of malign, nefarious or even opportunistic cyber criminals or cyber actors could get hold of it, and they have tactics,” Joshi said.

‘No significance’

Downing Street would not comment on the revelation that Burnham exchanged messages with the impersonator, citing “national security.”

One person briefed on the communications said a “few messages” were exchanged after the PM entered No. 10 but insisted they were “of no significance.”

It is unclear how the fraudster obtained Burnham’s number. POLITICO could not find it published online.

British officials initially feared Wiles’ phone had been hacked again. But a White House official said: “This incident had nothing to do with the Chief of Staff’s devices being hacked.”

It is not clear whether Burnham will change his phone number, as Boris Johnson did after the Popbitch newsletter revealed in 2021 that the then-prime minister’s details had been sitting online for years.

‘Full of traps’

The episode has sharpened questions over whether Burnham — who built his political brand on his informal style and being more approachable than other prime ministers — can carry on that way in No. 10.

A former national security adviser, granted anonymity to speak frankly, said the prime minister needs to “get into the habit” of having his security staff verify that messages reaching him are authentic.

National Security Adviser Jonathan Powell “could have phoned the White House in five minutes and checked whether Susie Wiles genuinely was texting the prime minister,” they said.

“Being a domestic politician and going on listening tours around the U.K. is one thing, but when you engage in the international world, it’s full of traps and full of risks,” the former adviser added.

“What starts off as a very informal chat can quickly get into some kind of business, and you could give away key details of an upcoming trip or the movements of Donald Trump,” they said.

Former Defense Secretary Ben Wallace — himself targeted by imposters posing as Ukraine’s prime minister in 2022 — said the incident “demonstrates our adversaries are always looking for weak points in our communications.”

While Downing Street has said nothing significant was discussed in the exchanges between Burnham and the imposter, Wallace said “there is always a risk of kompromat” being obtained by hostile actors.

As technology, such as AI voice cloning, improves, these sort of incidents are going to “happen more and more,” Wallace added.

Others have urged Burnham not to change tack.

Guto Harri, Johnson’s former director of communications, said: “It’s only a threat and it’s only an embarrassment if they give something away — and it doesn’t seem that he’s done anything like that.”

Harri said it was “good to have someone big enough not to have his calls screened from everyone” as prime minister.

“I don’t think it’s healthy that the civil service wants to control all access to the principal. If they had their way, nobody would be able to talk to a prime minister without going through them,” he said.

“We can’t say that politicians are not living in the same world as us … and then moan about them speaking to people like a normal human being.”

Harri conceded a new number might be a “good idea,” giving the prime minister a “clean slate.”
