The Swedish presenter, who came to the UK to interview the singer about the European leg of her 'Femme Fatale' tour, said that "secret agreements" and the censoring of his questions "destroy[ed] all possibility of journalistic work".
"They deleted half of my questions that I had to send in advance," he told Nojes Bladet.
"I could not ask about her co-operation with Swedish songwriters, I could not ask about Miley Cyrus or Selena Gomez, Britney's successors in the Disney industry.
"I could not ask about Chris Crocker's world-famous 'Leave Britney Alone' clip, and they had even deleted the question 'What do you hope the future will bring?'"
When asking the star if she felt "over-protected", he said: "The interview abruptly ended. And I do not believe a word of her response."
Spears is currently on the European leg of her worldwide jaunt. She is due to play eight arena shows in the UK next month.
The singer recently defended the plotline of the music video for her new single 'Criminal', which sees Spears and her boyfriend Jason Trawick holding a London cornershop at gunpoint
