The World Health Organization (WHO) is the favourite to receive the Nobel Peace Prize for 2021 when the winner is announced in Oslo on Friday.
It is one of the world's greatest accolades - previous winners have included Malala Yousafzai, Nelson Mandela and the Dalai Lama - but is not always easy to predict.
The Nobel committee asks academics, scientists, former winners and politicians to submit nominees and this year there are a record-breaking 329 up for the prize.
The WHO is a strong candidate for the central role it played in co-ordinating the international response to the Covid-19 pandemic. That said, it was in the running last year for the same reason and lost out to the World Food Programme.
Press-freedom watchdogs Reporters Without Borders come next in the betting at 8/1.
Prize for Navalny would be blow to Putin
A Nobel Prize for Alexei Navalny 12/1 would make big headlines around the world.
The Russian opposition leader and Putin critic has been nominated for fighting corruption in his country. He survived a poisoning last year and recovered in Berlin before bravely returning to Russia. Upon his arrival he was arrested and in is currently serving a sentence - for charges widely believed to be politically motivated - in a penal colony.
Victory for Navalny would infuriate Putin and be boost to the opposition in Russia.
Another opposition politician in that part of the world, Belarusian human rights activists Sviatlana Tsikhanouskaya, is 12/1.
Then there's Greta Thunberg, the Swedish teenage climate activist, who was tipped to win last year and in 2019. She's 16/1 to make it third time lucky.
Two political leaders - US president Joe Biden and New Zealand's PM Jacinda Ardern - are available to back at 20/1.
Both would probably have been shorter prices earlier in the year. For Biden, things have soured since the US's widely-criticized withdrawal from Afghanistan, while Ardern's handling of the pandemic appears to be unravelling as New Zealand faces a surge of the Delta variant.
