The UK Government has begun an inquiry into the leaked emails from UK ambassador, Sir Kim Darroch, which called the Trump administration ‘inept’ and ‘uniquely dysfunctional’.

The Foreign Office says the leak on Sunday was ‘mischievous’ but did not deny the accuracy of the memos, and a formal investigation into the leak will be launched.

Conservative MP Tom Tugenhadt says whoever was responsible for the leak must be prosecuted, as diplomats must be able to communicate securely with their governments.
