Presenter Martin Devlin has resigned from Radio Live's Breakfast show with immediate effect.
Devlin - who has hosted the show for two years - said he did not enjoy presenting "hard news".
"I've learned a huge amount and am really grateful for the opportunity to have spent timedoing 'hard news' but I have to say that I really don't enjoy it."
"News is serious, is taken seriously and I think most people believe it should be presented seriously and I'm just not that guy," he said.
In a statement, Radio Live said comments previously attributed to it in the Herald that Devlin was getting poor ratings were inaccurate and not the reason for his departure.
In a statement, the station said: "Both parties agree that unfortunately it just hasn't worked out and it's both responsible and appropriate to acknowledge this and move on.
"Radio Live wishes Martin the best for his future career, whatever form it takes."
