The London Metropolitan Police have demanded whoever is responsible for the leak of communications, which was widely condemned by US President Donald Trump, turn themselves in. Assistant Commissioner Neil Basu said: “Following a cross-government investigation led by the Cabinet Office a Gateway Process has occurred today with the Metropolitan Police into the alleged leaking of official communications involving Sir Kim Darroch. As a result the Metropolitan Police Counter Terrorism Command, who take national responsibility for investigating allegations of criminal breaches of the Official Secrets Act, has launched a criminal investigation.
“Given the widely reported consequences of that leak I am satisfied that there has been damage caused to UK international relations, and there would be clear public interest in bringing the person or people responsible to justice.
“The investigation will be reviewed at every stage to ensure a proportionate investigation is undertaken.
“I would say to the person or people who did this, the impact of what you have done is obvious.
