Oslo - Pope Francis and a line-up of anti-nuclear campaigners headed lists of favourites to win the 2015 Nobel Peace Prize on the eve of Friday's announcement.
The Geneva-based International Campaign to Abolish Nuclear Weapons (ICAN) was named as a leading contender for the $972 000 prize by Norway's state broadcaster NRK and by Nobeliana, a website run by historians who specialise in tracking the award.
NRK said Pope Francis' opposition to nuclear weapons boosted his chances, alongside his help in brokering a deal between the United States and Cuba, and his encyclical on climate change. Nobeliana mentioned his calls for social justice.
Both organisations also highlighted Setsuko Thurlow, a survivor of the nuclear bombing of Hiroshima, while Nobeliana picked out Sumiteru Taniguchi, a survivor of the atomic attack on Nagasaki.
