RTÉ 2FM has announced that Jennifer Zamparelli is moving from Breakfast Republic to host her own show on the station, with Jenny Greene leaving 2FM.
Zamparelli's new programme will air weekdays from 10:00am-1:00pm from June 10 as part of 2FM's new schedule; the slot has been occupied by Greene and co-host Nicky Byrne.
2FM said that the departing Greene will still perform as part of the previously scheduled RTÉ Concert Orchestra shows this summer. As previously confirmed, Byrne is leaving 2FM to return to the reunited Westlife.
Greene, who also presents The Electric Disco on 2FM, said she had "decided to say farewell to 2FM" with "a very heavy heart".
"Having started off in the evening time and progressing on to a very successful day time show, going back to the evenings on 2FM just doesn't feel like the right decision for me both personally and professionally," she wrote on social media.
Co-host Byrne tweeted that Greene is "simply the best".
"I will miss 2FM terribly, especially Jenny with her radio wisdom, nerves of steel and a cracking sense of humour," he wrote.
Paying tribute to Byrne and Greene, 2FM boss Dan Healy said: "Nicky and Jenny have been a massive part of 2FM over the past five years and have been an important part of changing the 2FM brand to what it is today and I would like to thank them both for delivering five years of great radio.
"I wish Nicky the best as he returns to a worldwide tour with Westlife and Jenny the best in her future endeavours."
Looking forward to her new show, Zamparelli said: "I'm delighted to have this opportunity and even though I'll miss my pals on Breakfast Republic I will still be popping in to distract them and sabotage their show on a daily basis.
"I may not be on the breakfast show anymore but the deal is I still have to get them coffee every morning. Thrilled for the opportunity, thrilled to do something different and thrilled to be getting up slightly later then stupid o'clock every morning."
Healy said Zamparelli is "ready to spread her own wings and move into her own space".
"I believe Jen will appeal to young audiences as she has that instant likeability and humour," he added.
"Our audiences have reacted in an overwhelming positive way towards her."
