Ambassador leaks are a "matter of regret", Britain tells U.S.

Britain's government has told Washington that leaks of memos in which the UK ambassador described U.S. President Donald Trump's administration as "dysfunctional" were a matter of regret, the Prime Minister Theresa May's spokesman said on Monday.

The memos from Kim Darroch, the ambassador to Washington, were leaked to a Sunday newspaper, annoying U.S. President Donald Trump and triggering demands on the British side to find out who had disclosed them.

"Contact has been made with the Trump administration setting out our view that we believe the leak is unacceptable. It is, of course, a matter of regret that this has happened," May's spokesman told reporters.
