Donald Trump will decide whether to pull the US out of the Paris Agreement on fighting global climate change next week, after resisting intense pressure from the rest of the Group of 7 countries not to abandon the deal.

The rest of the G7, including Britain, spent three days urging the President to stick with the accord, first in meetings in Brussels and then at a two-day summit in the clifftop town of Taormina in Sicily.

The President, who has previously described man-made climate change as “a hoax”, made the announcement in characteristic style – with a tweet. “I will make my final decision on the Paris Accord next week!” he wrote, pre-empting the final communique issued by the G7 leaders at the conclusion of the summit.
