Sweden's Loreen thanked voters before performing her winning track Euphoria
Favourite Loreen has triumphed for Sweden at the 57th Eurovision Song Contest, with her club track Euphoria.
British entry Engelbert Humperdinck, who opened the contest with his ballad Love Will Set You Free, finished second from last - despite high hopes.
The 76-year-old said he "did the best for my country".
"I've had many highs in my career and Eurovision has been a wonderful experience," he said.
"I want to thank everybody, especially my fans around the world for their words of support.
"I did the best for my country, the rest was out of my hands."
However, at least the British star was spared the humiliation of 'nil points'.
Poor draw
The crooner, who has sold more than 150 million records worldwide, received just 12 points - from Estonia, Latvia, Belgium and Ireland.
The UK has not won since 1997 and has come last three times in the past 10 years.
There were high hopes for Humperdinck - affectionately known as "The Hump" - given his huge global fanbase, but his draw as first to sing in the contest seemingly proved detrimental.
Viewers often tune in late and miss the early contenders.

"I love you so much. Thank you for believing in me," the 28-year-old Swede told her supporters, as she took to the stage to sing one final time.
"I wouldn't have been able to do it without you."
Ireland, who were represented by Jedward for the second year in a row, came 19th - with 46 points - an unexpected slump on their previous performance in 2011, which saw them come eighth.
