Trump set to clash with other G7 leaders over refugees, trade and climate

Disagreements with US are so fundamental that Sicily summit might not be able to issue communique

Divisions between Donald Trump and other members of the G7 at the summit in Sicily have become so broad and deep that they may be forced to issue a brief leaders' statement rather than a full communique, dashing Italian hopes of engineering a big step forward on migration and famine.

With the US president apparently reluctant to compromise with European leaders over climate change, trade and migration, the European council president, Donald Tusk, was forced to admit on Friday that this would be the most challenging G7 summit in years and there was a risk of events spiralling out of control.
