One of the world's most prestigious prizes honouring peacemakers will be announced on October 6.

No less than 318 people and organisations are nominated for this year's Nobel Peace Prize.

The nominations are supposed to be secret, but the White Helmets search-and-rescuers in Syria, Pope Francis, and US President Donald Trump are expected to be on the list.

Previous winners have been controversial, including Trump's predecessor Barack Obama, Vietnam war figure Henry Kissinger, and now Myanmar's Aung San Suu Kyi.

Who are the other questionable winners from the past?
