Russia could cut gas supply to Finland ‘on Friday’ following decision to join Nato

Finnish politicians have been warned they could be cut off from Russian gas as early as Friday just hours after the country said it wanted to join Nato, reports have claimed.

The warning came just hours after Russia said it would be forced to take “retaliatory measures” after Helsinki signalled it would seek to become a Nato member.

Russia’s foreign ministry said Finland’s application, announced on Thursday, is a “radical change” in the country’s foreign policy.
