The corresponding statement is published on the website of the London police.

"Publishing leaks of messages, knowing how much damage they have caused or can cause, can also be a criminal case," said Basu.

He advised the media "not to publish leaked government documents, which may already be at their disposal or that they may be offered, as well as transfer them to the police or return them to their rightful owner, the government of Her Majesty."

Earlier, the British police launched an investigation into the diversion of diplomatic correspondence by the British Ambassador to the US, Kim Darroc.
