The Metropolitan Police has apologised to victims of the Westminster “honeytrap” scandal after it accidentally sent an email which named all of them.
The force said it was referring itself to data watchdog the Information Commissioner over the breach.
The Met is investigating flirtatious messages being sent by someone calling themselves “Charlie” or “Abi” to as many as 20 people including MPs, staffers and political journalists.
A detective sent potential victims an email updating them on the case, but inadvertently copied in all of those involved, revealing to the recipients their names and email addresses.
The email was sent on Friday afternoon to update 18 people that the date a suspect would have to answer bail was being changed because of a fire at Charing Cross police station.
However, the sender, a detective sergeant in the Met’s Diplomatic and Parliamentary Protection unit, included the recipients’ names in the CC section of the email, rather than BCC, which would have concealed their identities.
The has seen the email, and will not be naming those included as recipients, however they include members of parliament, political journalists and Commons staff.
One of the alleged victims told the : “It’s infuriating to have your personal details released in this way.
“It will make me think twice about reporting anything to the Met again.”
Another alleged victim said: “To be honest, I feel sickened to discover that my name has now been circulated in relation to this whole saga.
“Every one of us listed is a victim who now has to weigh up the risk to our reputations of being associated with this all for simply doing the right thing and coming forward when we were encouraged to do so.
“There has been no communication to say that this error has happened – and all for what is essentially another holding email. It’s exhausting.”
In a statement, Scotland Yard said: “An email relating to an ongoing investigation was sent in error today [Friday].
“We recognise the impact on those involved and apologise sincerely for any distress.
“A referral to the Information Commissioner’s Office has been made and we await advice on next steps.
“Officers will be reaching out to those impacted to personally apologise and provide reassurance.”
