Britain is prepared to deploy troops to protect Nato allies in Europe should Russia invade Ukraine Boris Johnson said, as he warned Vladimir Putin faces “ferocious” Ukrainian resistance.

The Prime Minister also said the UK and its allies stand ready to impose “heavy economic sanctions” on Russia and voiced fears that any invasion would result in “bloodshed comparable to the first war in Chechnya or Bosnia”.

MrJohnson told MPs the UK will not hesitate to “toughen our national sanctions” against Russia in response to “whatever President Putin may do”.
