Europeans to test Trump on Iran deal risks

European leaders will warn U.S. President Donald Trump at Tuesday’s G7 summit that a superficial interim Iran deal risks entrenching Tehran's nuclear and ballistic missile programmes, while also pressing him to rethink his Ukraine strategy.



The June 15 to 17 gathering in Evian-les-Bains, on the shores of Lake Geneva, brings together the leaders of France, Britain, Canada, Germany, Italy, Japan and the United States, alongside the European Union.



Trump arrived in France on Monday evening buoyed after Washington and Tehran agreed a preliminary deal to end the wider conflict, with a formal signing targeted for Friday.



"The Iran deal will bring a lot of success," Trump said shortly after he arrived in Evian-les-Bains.



French President Emmanuel Macron said the priority was to ensure there is a "solid, serious agreement that is finalised."



He said a Tuesday lunch session would focus on the safe reopening of the Strait of Hormuz, including a possible Franco-British-led maritime mission and identifying alternative energy routes bypassing the waterway. Trump said the strait would be "completely open" on Friday.
