Featuring 167 images, the exhibition includes the World Press Photo of the Year, shot by Samuel Aranda, as well as select photographs from the competition's nine other categories.

This year marks the 55th year of the prestigious World Press Photo, which saw 101,254 images submitted from 124 different countries. The exhibition itself travels to more than 45 countries, maintaining the importance of the award in both recognising the work of photojournalists worldwide and reflecting the most significant events of the past year. As such, the work this year is heavily focused on the unrest associated with the Arab Spring, as well as the Japanese tsunami and the massacre on Norway's Utøya Island.

The winning image, shot by Aranda in Sanaa, Yemen, portrays a woman holding her son, who had just been attacked with tear gas while joining protests in the capital. "I think it's really important when you receive such an award to remember that all this work is for the people we're documenting," Aranda told BJP in February. "What I would really like is for this photo to help the people of Yemen. I think it's a country that is often forgotten."

The exhibition runs from 09 to 27 November at the Royal Festival Hall, Southbank Centre, London. Entry is free.
