Ukraine’s president has said joining NATO would guarantee his country's security. He says it will not be easy, but there is no other path for Ukraine. The UK's defence secretary, Ben Wallace, said Russia will be judged by its actions. ‘We've seen the opposite of some of Russia’s statements. We've seen an increase of troops over the last 48 hours up to 7,000, we've seen a bridge constructed from Belarus into Ukraine - or near Ukraine. At the moment Russia’s troop build-up continues.’ Wallace says NATO is united and is ‘deadly serious on how we're going to face the threat being posed to Ukraine and potentially our security’. Speaking after a meeting of defence ministers, he says it's becoming ‘tragically normal’ for Russia to use ‘malign activity and threats to try and get its way’ and Europe has to respond to that, adding, ‘This is a real challenge to the stability of Europe.’
