RTÉ 2FM presenter Jenny Greene has said she is leaving the station with "a very heavy heart" following Tuesday's announcement of changes to the morning line-up.
From June 10, Jennifer Zamparelli is taking over the 10:00am-1:00pm slot, which had been home to the show Greene co-hosted with Nicky Byrne. He is leaving 2FM to return to the reunited Westlife.
Writing on social media, Greene said: "It is with a very heavy heart that I have decided to say farewell to 2FM, 12 years after [former Head of 2FM] John Clarke gave me the opportunity to host my own show on Friday night. Soon after [producer] Ian Wilson took me under his wing and secured me a Saturday night show and he gave me the freedom to create my own brand and vision with The Electric Disco. I can never thank him enough for the belief he had in me.
"The Electric Disco has given me the platform for my first love, which is and always will be djing. The success of the show has led to an album release, a nationwide tour, an Australian tour in 2013 and most recently I have had the privilege of performing these tracks live, with the RTÉ Concert Orchestra.
"When [current Head of 2FM] Dan Healy pitched the idea of working alongside Nicky Byrne in 2014, never in a million years did I imagine that such a risky pairing would be so successful or that I would find a friend who supports me on and off air. He is my rock."
After listing the highlights of her time on 2FM, Greene concluded by saying: "Having started off in the evening time and progressing on to a very successful day time show, going back to evenings on 2FM just doesn't feel like the right decision for me both personally and professionally.
"So I want to thank all the loyal listeners who tuned in every day on 2FM and those who helped me along the way in RTÉ, you know who you are. To quote the late, great Terry Wogan, 'there's never a right time to leave something you love, but there might be a wrong time if you hang on too long'."
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.
"I really couldn't have wished for a better captain to have learned under," he added, saying Greene "taught me so much through the years".
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."
2FM said that the departing Greene will still perform as part of the previously scheduled RTÉ Concert Orchestra shows this summer.
