By Tom Mctague, Mail Online Deputy Political Editor David Cameron and Russian President Vladimir Putin held face-to-face talks today for the first time since the crisis in the Ukraine. The Prime Minister met Mr Putin in Paris at the Charles De Gaulle Airport ahead of tomorrow's D-Day commemorations in Normandy. It came after Mr Putin was warned that he has one month to end Russia's destabilisation of Ukraine or facing crippling economic sanctions. After the meeting Mr Cameron said he gave the Russian President a 'very clear and firm set of messages' during the talks and said the current situation is 'not acceptable'.
