President Putin’s brazen visit to Kaliningrad in the heart of Europe this week was a very clear provocation. Whilst not a direct threat to Nato, it should serve as a wake up call to those who look at the crisis unfolding on the Continent and think this is all business as usual, with Russia now stalled in Ukraine and the war settling into a stalemate.
The UK must keep Ukraine at the top of the agenda "because they re fighting for us out there", a former NATO secretary general has told Sky News. Meanwhile, Vladimir Putin made his first remarks on the military plane crash this week - and accused Ukraine.
Britain should reassess the size of its armed forces in response to threats from Russia and the crisis in the Middle East, one of Joe Biden’s defence ministers has said.
