Russian dissident Alexei Navalny, the World Health Organization and climate campaigner Greta Thunberg are among those nominated for this year's Nobel Peace Prize, all backed by Norwegian lawmakers who have a track record of picking the winner.

Thousands of people, from members of parliaments worldwide to former winners, are eligible to propose candidates. Nominations, which close on Sunday, do not imply an endorsement from the Nobel committee.

Norwegian lawmakers have nominated the eventual laureate every year since 2014, with the exception of 2019, said Henrik Urdal, Director of the Peace Research Institute Oslo. "The pattern from recent years is quite stunning."
