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.”
