The U.K.'s top diplomat in the U.S. views President Donald Trump as "inept," "insecure" and "incompetent," according to leaked diplomatic cables.
Kim Darroch, Britain's ambassador to Washington, D.C., made the highly critical comments about the president and his administration in a series of memos to London.
NBC News has confirmed the authenticity of the documents. In a statement, a spokesperson for the British Foreign and Commonwealth Office said "a formal leak investigation will now be initiated."

The leaks provide a rare insight into how a key U.S. ally views the Trump administration behind closed doors.
The memos were critical of Trump's economic policies, claiming they could wreck the world trade system, described conflicts within the White House as "knife fights" and warned "the worst cannot be ruled out" in regard to allegations of Trump's collusion with Russia.
