David Cameron was mocked online today after posting a picture of himself on Twitter in which he was apparently taking a phone call from Barack Obama about the Ukraine crisis.
Adopting a serious expression, the Prime Minister was seen speaking to the US President about Russia's moves towards a military intervention in Ukraine.
On his official Twitter account, the photo was captioned: "I've been speaking to @BarackObama about the situation in Ukraine. We are united in condemnation of Russia's actions."

Meanwhile in his picture, Stewart held a tub of anti-bacterial hand wipes to his ear, saying: "I'm now patched in as well. Sorry for the delay."
