UK PM: In Event Of Russian Invasion UK Will Contribute To NATO Units

UK Prime Minister Boris Johnson has just delivered a statement to the House of Commons on the Ukraine crisis (link to livestream here).

• 'I shudder to contemplate the tragedy that would ensue [from a Russian invasion]...No one would gain from such a catastrophe'
• 'Russia's goal is to keep NATO forces away from her borders. If that is her goal, then invading Ukraine could scarcely be more counter productive.'
• In the event of a Russian invasion the UK would impose sanctions 'heavier than anything we have done before against Russia'. UK would also "look to contribute to any new NATO deployments to protect our allies in Europe"
• UK gov't “can not accept the doctrine implicit in Russia’s proposals that all states are sovereign but some are more sovereign than others.....We must not bargain away the vision of a free Europe".
