Eurovision Song Contest broadcaster Ken Bruce says it was a mistake to give the public the chance to select the entry for the singing competition.
But the Radio 2 presenter, who is hosting the station's coverage of the contest on Saturday, said: "It's better at the moment we don't give the choice of UK entry to the public. Sometimes there's a devilment in the public, thinking, 'I'm not going to vote for that because I know it's the one they want'.
"Instead, they vote for the most obvious Euro-kitsch song. We need to put in a song that we can say, 'Yes, that's a good song, with a professional singer'."
The broadcaster told the Radio Times: "I see my role as totally partial - the UK are supposed to win. It would be terrible if I weren't allowed to be partial and if people don't vote for us who I think should. Like last year, Malta didn't vote for us, and I said, 'Right, well, we'll have the George Cross back'. You vote for us because we're good people."
The DJ attributed his successful weekday Radio 2 show - which has 8.1 million listeners - to poor quality daytime TV.
"To be frank with you, daytime TV is so rubbish, we do very well as a result, I'm sure," he told the magazine. "If they suddenly put something great on the telly, then I'd be worried."
