Authorities in the UK have reportedly identified the suspect behind the leaked memo that provoked a diplomatic spat with President Donald Trump.
According to the Sunday Times, which cited unnamed government sources, a suspect has been identified.
The Mail also published more leaked documents from Kim Darroch, defying a police warning that publishing such material could be a criminal offence.
The government has already opened an internal inquiry into the publication of the memos, which saw the US ambassador refer to Trump as "clumsy and inept".
