TV and radio presenter Sarah-Jane Mee is to leave Heart's breakfast show and the West Midlands.
Just over a year after joining the station Ms Mee, who is also a sports presenter for ITV Central, has said that it is time for her to move back home to London.
The 28-year-old presenter, who worked alongside Ed James, said she wanted to pursue new television opportunities nearer to home and be to her personal life, friends and family.
Luis Clark, Heart's programme director said: "We are sad to see Sarah-Jane go but she does so with our best wishes.
"Any change is an opportunity and we will take Heart Breakfast forward with an exciting new co-host. Sarah-Jane is with us until late Spring and we will be announcing plans in the near future."
Ms Mee, who stepped into the role of Heart breakfast's co-presenter in December 2006, said: "I'll miss Ed and the team but the time is right for me to go back home to London. I have had a great time entertaining the Midlands - I will be sad to leave but I will enjoy lying in past 5am!"
In the face of dwindling radio audiences Heart - categorised as a "heritage" station in the West Midlands - has been fighting to keep its audience share and title of most listened to station in the region.
The last quarterly figures from industry body RAJAR were relatively flat, with average weekly audience up slightly to 783,000 from 776,000 previously.
The station has recently launched a new television advertising campaign and said it hoped to see a rise in listeners in the next quarter.
Last week, it was revealed the Heart-owner Global Radio had approached BRMB parent group GCap Media with a bid valuing the firm at around £313 million.
GCap turned down the Global Radio offer of 190p a share saying it "significantly undervalued the company".
