Sir Kim Darroch, who was forced to step down as Britain’s Ambassador to the US last week over a set of leaked memos, sent a diplomatic cable to Downing Street saying Donald Trump had abandoned the deal for “personality reasons” because it had been agreed by Barack Obama. The cable also described how the then Foreign Secretary Boris Johnson failed to save the deal following a last-minute dash to Washington to meet US Secretary Mike Pompeo in a desperate bid to make the US leader change his mind.
The explosive diplomatic cable was set to London just hours after Mr Johnson returned to the UK, according to the Mail on Sunday.
The claims come after Scotland Yard was at the centre of a furious row over press freedom after warning journalists not to publish any more leaked cables from Britain’s US ambassador Sir Kim Darroch.
Politicians and journalists condemned the “heavy-handed” actions of the Metropolitan Police following the warning that any further release could be a “criminal matter”.
However, the force defended its actions, saying it had a duty to enforce the law in relation to the Official Secrets Act (OSA).
The row erupted after the Met announced on Friday it was launching a criminal investigation into the leak of the cables, which resulted in Sir Kim’s dramatic resignation.
Sir Kim announced on Wednesday he was resigning, saying his position had become “impossible” following the leak of his dispatches in which he described Donald Trump’s White House as “inept” and “dysfunctional”.
His comments drew a furious tirade from the president who denounced him as a “very stupid guy” and a “pompous fool”, and said the White House would no longer deal with him.
Sir Kim’s career was left hanging in the balance after he questioned whether the White House “will ever look competent” in a string of private messages which were made public.
Sir Kim also referred to “incoherent, chaotic” US policy on Iran and questioned Mr Trump’s publicly stated reason for calling off a retaliatory air strike against Tehran following the downing of an American drone.
The US and Iran have been at the brink of World War 3 over tensions in the Gulf, and Mr Trump stated that he called off a planned air strike with minutes to spare because of the potentially high number of casualties.
But Sir Kim said that the explanation “doesn’t stand up” and suggested it may have been motivated by Mr Trump’s focus on the 2020 re-election campaign and his previous promises not to involve the US in foreign conflicts.
He said: “It’s more likely that he was never fully on board and that he was worried about how this apparent reversal of his 2016 campaign promises would look come 2020.”
Sir Kim said it was “unlikely that US policy on Iran is going to become more coherent any time soon” as “this is a divided administration”.
