REUTERS/Evelyn HocksteinThe winner of the 2025 Nobel Peace Prize will be announced on Friday, in a year overshadowed by a months-long campaign by US President Donald Trump to win what is arguably the world's most prestigious award. "If you look at Alfred Nobel's will, it emphasizes three areas: one is the achievements regarding peace: brokering a peace deal," she said. HOW THE NOBEL COMMITTEE DECIDESInsiders say the award follows a year-long, deliberative process, during which candidates' strengths and weaknesses are debated by the five-strong committee. The Nobel committee says it is used to working under pressure from people, or their supporters, who say they deserve the prize. "All politicians want to win the Nobel Peace Prize," Frydnes, the Nobel committee leader, told Reuters.
