By Matt Chorley, Mailonline Political Editor Russian President Vladimir Putin must end the 'festering and dangerous crisis' in Ukraine or face the consequences, David Cameron warned today. Invoking the outbreak of World War Two, the Prime Minister said Europe must not forget the 'consequences of turning a blind eye when big countries bully smaller countries'. He insisted Russia 'needs European markets far more than we need Russian markets', as he warned it would be 'unthinkable' for France go ahead with selling warships to Putin. It came after Chancellor George Osborne warned failure to stand-up to Russia  risks causing harm to the British economy.
