Floral fail: David Cameron caught out, wearing a poppy that was a bit photoshoppy

On Monday afternoon, Dylan Morris, a Twitter user in the British seaside town of Plymouth, noticed something unusual. A photograph of British Prime Minister David Cameron on the 10 Downing Street Facebook page appeared to have been digitally altered to include a flower pinned to Cameron's lapel.

Morris checked with another photograph. Yes, that poppy had clearly been added in.

Why add the poppy? In countries around the world, a poppy is worn during the start of November to commemorate fallen soldiers. The symbolism is potent: The flowers are said to have grown in

Flanders, Belgium, where soldiers fought and died during World War I.

The trend seems to be especially popular in Britain, where plastic poppies are sold before Remembrance Day on November 11 by the Royal British Legion to raise money for army veterans. Almost all public figures - politicians, journalists, sportsmen or otherwise - are expected to wear poppies in public during November, and they face scrutiny and controversy if they do not. Just this weekend, actress Sienna Miller was criticised for not wearing a poppy during a television appearance.

Exactly how a poppy came to be photoshopped onto Cameron's lapel is unclear. When the Independent newspaper asked, it was told, “It was just an oversight.” The photograph was swiftly deleted from the 10 Downing Street Facebook page and replaced with one of Cameron sporting a real poppy.

Of course, it was far too late. Cameron was swiftly ridiculed on social media for the photograph.
