Donald Trump has denied claims he left the G7 summit early to work on a ceasefire between Israel and Iran, insisting the reason was “much bigger”.

The president returned to Washington after just one day in Canada, instructing the National Security Council (NSC) to be ready in the Situation Room upon his return.

Emmanuel Macron, the president of France, suggested Mr Trump left early to work on a ceasefire between Israel and Iran.

Mr Trump hit back on Truth Social: “Wrong! He has no idea why I am now on my way to Washington, but it certainly has nothing to do with a Cease Fire. Much bigger than that. Whether purposely or not, Emmanuel always gets it wrong. Stay Tuned!”

There has been speculation that Mr Trump has intelligence that Iran is about to strike a US base in Iraq, raising fears America could be dragged into the war.
