Ukrainian singer Jamala snatched victory from arch-rival Russia to win the Eurovision song contest on Saturday, adding a touch of political drama to the annual kitsch extravaganza.

After a tense vote count, during which it seemed Australia was going to run away with the crown until the audience votes came in, Jamala was declared the winner in Stockholm after a heartfelt performance of 1944, a song about the deportations of Crimean Tatars during World War II.

Jamala's entry - which stirred controversy over perceived veiled criticism of Russia's recent annexation of Crimea - scored 534 points, closely followed by Australia's Dami Im with 511 points, the juries' favourite.

The hotly tipped former Russian child star Sergey Lazarev came in third with 491 points.

In Moscow, public TV channel Rossiya 1's commentators congratulated Jamala on her win, without mentioning the Crimean Tatars.

They said Jamala's song was "about her family members", without offering further details.

Jamala herself described the win as "amazing".

"I was sure that if you sing, if you talk about truth it really could touch people," the 32-year-old said at the winner's press conference.

The stunning turnaround in the final minutes of the show capped an eventful 61st edition of the love-it-or-hate-it kitsch fest, which was expected to be the most-watched Eurovision since the event was first staged in 1956.

Scores were decided by national juries as well as viewers. In an attempt to give the outcome a more democratic feel this year, fans were given the final say - adding some last-minute suspense to the contest.

Among the evening's other highlights was a guest appearance by US pop star Justin Timberlake, who entertained the crowd with his hit Rock Your Body before performing his new single, the upbeat Can't Stop the Feeling, which itself wouldn't have sounded out of place in the Eurovision line-up.

In another sign of the contest's growing appeal, Eurovision was for the first time broadcast live in the US on the Logo channel, which is aimed at the LGBT (lesbian, gay, bisexual and transgender) community.

The show was also live-streamed on YouTube, giving Google a piece of a pie once reserved for European public broadcasters.

"The Eurovision Song Contest is now a truly global phenomenon," producer Jon Ola Sand said, amid expectations that the show will push last year's record of 197mn viewers worldwide.

'In my blood'  

Characterised by critics as a potpourri of bizarre performance antics, special effects and cheese, the light-hearted contest usually tries to avoid controversy and steer clear of geopolitics but this year was always going to be different.

Political leaders in Moscow and Crimea had initially sought to get Jamala's song disqualified, arguing that it criticised Russia's annexation of the Black Sea peninsula in March 2014.

The jury approved the lyrics nonetheless, setting the stage for a monumental confrontation.

Inspired by Jamala's great-grandmother's story, 1944 recounts the deportation of the Crimean Tatars by Soviet strongman Joseph Stalin, and she sings it partly in the Tatar language, she says, because "it's in my blood."

The song has resonance for contemporary Ukraine, where memories of that horror were revived by Russia's seizure of Crimea, and Jamala's poignant lyrics tell the story of a people with a history of persecution that continues to this day.

Ukrainian President Petro Poroshenko was among the first to congratulate Jamala on her victory.

"Yes!!!" Poroshenko tweeted. "An unbelievable performance and victory! All of Ukraine gives you its heartfelt thanks, Jamala."

Ahead of showtime, bookies had tipped Russia's Lazarev and his catchy You Are the Only One tune to win the contest between 26 finalists - 25 Europeans and one Australian.

Lazarev, popular in his own country and eastern European nations, has built an eventful career as a singer, actor and TV host.

He has also drawn admiration from gay rights campaigners for speaking out against his country's climate of homophobia.

Earlier this month he told Sweden's QX gay magazine that he was happy for fans to wave rainbow flags at his performance, saying he respects his gay fans and they respect him.

Guest competitor Australia also lived up to its billing as a frontrunner, cementing its reputation as a country to be reckoned with in its second year of competition after first being invited to last year's anniversary edition.

South Korean-born Dami Im, 27, a classically trained pianist and former X-Factor winner, won over the national juries with her slick performance of Sound of Silence, but in the end it was the viewers who decided it wasn't quite enough to beat Jamala's performance.
