London, July 7 (TIWN) In leaked emails, the UK's Ambassador to Washington Kim Darroch labelled American President Donald Trump's administration as "inept, insecure and incompetent", a media report said on Sunday.

Sir Kim Darroch said that the White House was "uniquely dysfunctional" and "divided" under Donald Trump.

But he also warned that the US president should not be written off.

The Foreign Office said the leak of the memos to the Mail on Sunday was "mischievous" but did not deny their accuracy.

The White House has not yet responded to the revelation of the contents of the memos, but it could test the so-called "special relationship" between the US and UK.

In the messages, Sir Kim said: "We don't really believe this administration is going to become substantially more normal; less dysfunctional; less unpredictable; less faction-riven; less diplomatically clumsy and inept."

He questioned whether this White House "will ever look competent".
