Piers Morgan will not face sanctions after asking a Christian who opposed same-sex marriage whether he was a "homophobe".
Dozens of complaints were made against the Good Morning Britain presenter by viewers who felt the remarks were offensive and discriminatory towards Christians and implied all Christians were homophobic.
However the media watchdog Ofcom rejected the complaints.
Morgan made the comments in an interview with Richard Page, a Christian magistrate who was sacked after he voiced opposition to adoption by same-sex couples.
Page was removed by justice secretary Michael Gove and the Lord Chief Justice Lord Thomas in March because he was "biased and prejudiced against single sex adopters" and his views brought magistrates' courts into disrepute.
During the interview last month on ITV's breakfast show, Morgan asked Page if he was in favour of same-sex marriage. When Page replied that he was not Morgan said: "So you're a homophobe then?"
A total of 70 complaints were lodged against Morgan for his comments but Ofcom has announced it will not censure him.
"We assessed a number of complaints that Piers Morgan's tone was offensive and discriminatory towards Christians in an interview," said a spokesman for Ofcom.
"We noted that the interviewee was given several opportunities to respond. He stated he was not homophobic, and set out reasons why. Overall, the interview was balanced and we found no evidence of discrimination."
