Cameron tweeted a photo of him on the phone to US President Barack Obama while the leaders were discussing developments in Ukraine.

But what was intended to be a serious snapshot of diplomacy at work quickly became the subject of caption competitions and inspired dozens of Twitter users' own interpretations of the photo.

Celebrities including actor Sir Patrick Stewart and American comedian Rob Delaney uploaded their own photos poking fun at the prime minister's selfie as did hundreds of users across the world.

Attempts to recreate the shot soon went viral with dogs, an iron and a tube of toothpaste all used instead of a phone.

Here are some of the best responses to Cameron's tweet:
