Aled Jones will not appear on the BBC while the corporation investigates claims of inappropriate behaviour.
The Songs Of Praise presenter, 46, has denied allegations made in The Sun On Sunday that he sent inappropriate messages to a female colleague more than 10 years ago.
However, he has agreed to stay out of the limelight while a probe is under way.
A spokesman for Mr Jones said: “Whilst he accepts that his behaviour over a decade ago was occasionally juvenile, as was that of others, he never intended to harass or distress and he strongly denies any inappropriate contact.
“He is, however, deeply sorry for any upset caused and hopes this matter is resolved soon.”
The father-of-two found fame as a 12-year-old choirboy with the Christmas classic Walking In The Air and received an MBE in 2013 for services to music and broadcasting.
The BBC has declined to comment.
