US President Donald Trump has suggested Germany’s imports of Russian natural gas are a security concern, as he and other Nato leaders gather for a summit.

At talks in Brussels with Nato chief Jens Stoltenberg, he said it was a “very bad thing for Nato” that Germany was “totally controlled by Russia”.

German Chancellor Angela Merkel is to meet Mr Trump in the afternoon.

He suggested 70% of Germany’s gas imports were Russian; the latest official figure is from 50% to 75%.

In an earlier version of this story, the figure was given incorrectly as 50.75%.

The US president also accused Germany of failing to pay enough for Nato operations.

The Brussels summit comes less than a week before Mr Trump is due to hold his first summit with Vladimir Putin, in Helsinki, reviving concerns among US allies over his proximity to the Russian president.
