London, July 13 (RHC)-- London police are launching an official investigation into the leak of diplomatic cables that resulted in the UK ambassador to the US resigning his post over describing the Trump administration in disparaging terms.

On Friday, the London Metropolitan Police said that “there has been damage caused to UK international relations, and there would be a clear public interest in bringing the person or people responsible to justice.”

Cables from Sir Kim Darroch, the UK’s ambassador to the United States, were leaked to the Mail on Sunday last week. In the documents, Darroch described US President Donald Trump as “inept” and “incompetent” and his administration as “dysfunctional” and at risk of collapsing in “disgrace.”

Trump responded by attacking Darroch in a series of tweets, saying that the ambassador “is not well liked or well thought of within the US” and that his administration “will no longer deal with him.”

The incident has caused the British government considerable embarrassment, especially considering that the partnership between the two countries was just trumpeted during Trump’s state visit to the UK in early June.
