Press Association picture editor, Martin Keene, presents his selection of memorable pictures from its news archives from the past decade.
"John Giles knows the attraction of a great weather picture. The tram says Blackpool, the sea says storms. But come at low tide, or when the wind was blowing from another direction - there would be nothing of note to photograph. It's the perfect picture.
"Stefan Rousseau, who travelled extensively with Tony Blair, was there when the then PM met Libya's leader, Colonel Gaddafi. It's not a picture that anyone gazing into the crystal ball 10 years ago would ever have expected to see."
"This fleeting moment of a young shopper caught in the rain in Cheltenham by Barry Batchelor has been used countless times to summarise the washout summer of 2004 - and of some summers since. A moment either way and the picture would have never happened."
"On the day of the London bombings we sent photographers to the main locations, including Edgware Road Tube station where Edmond Terakopian photographed this man, bloodied and bandaged but carrying his newspaper. A worthy winner at the World Press Awards."
"Owen Humphreys's shot of Top Gear's Richard Hammond leaving Leeds General Infirmary after an accident while filming was one that everyone wanted to see. Owen knew Hammond was likely to leave by helicopter so found a vantage point in a nearby building."
"This picture by Cathal MacNaughton shows that good images can happen anywhere. This was in St James' Park in central London. Why does it work? It's something that few of us have ever seen before, and we all want to know - what happened next?"
"The Queen and her grandson, Prince William, at his passing out parade at the Royal Military Academy at Sandhurst was a picture that every photographer wanted to take. Lewis Whyld captured the moment perfectly."
"Martin Rickett took this picture a few days after David Cameron's 'hug a hoodie' speech and shows that it's important to be ready for a picture at any moment even when an event looks routine and unpromising."
"The Noughties was the decade of citizen journalism, when digital cameras and mobile phones were everywhere. Alistair Robertson was on the scene at Glasgow when a bomber tried to drive a car into the airport terminal."
"John Stillwell's picture of Prince Harry serving in Afghanistan was taken as a result of a remarkable media blackout over his presence on the front line."
