Sir Terry Wogan said he may quit as the BBC's Eurovision commentator, as the UK entry sung by former X Factor finalist Andy Abraham finished in last place.
Sir Terry cast doubt on his role after saying this year's results showed it was "no longer a music contest".
Sir Terry, who has commentated on the competition since the 1970s, told BBC News: "I don't want to be presiding over yet another debacle."
Abraham received 14 points for his song Even If, as Russia won with 272 points.
"Russia were going to be the political winners from the beginning," he told viewers at the end of his commentary on Saturday.
"I think it's tremendously disappointing from the point of view of the United Kingdom," he added.
"Andy Abraham gave, I think, the performance of his life with a song that certainly deserved far more points than it got when you look at the points that Spain got, that Bosnia-Hercegovina got - some really ridiculous songs."

Sir Terry said his producer, Kevin Bishop, was retiring after this year's contest.
"He and I have to decide whether we want to do this again," he said.
"Indeed, western European participants have to decide whether they want to take part from here on in because their prospects are poor."
On Sunday, Sir Terry added: "I'd like to think that the British music industry and [Eurovision organisers] the European Broadcasting Union will find some way of making the voting a little bit fairer."
UK'S EUROVISION RECORD
2008 - Andy Abraham, 25th place
2007 - Scooch, 22nd

Abraham received six points from San Marino - who were taking part for the first time - and eight from Ireland.
The singer said after the contest: "It's very easy to pick a country that's going to give another country 12 points. It's sad, it's really, really sad.
"It was all talked about beforehand and I decided that I was going to dismiss it. But it's very difficult to dismiss something that's right in your face."
Germany and Poland also received 14 points each, but they officially finished above the UK because their top scores in a single round were higher.
