RTÉ Radio 1 has announced a series of changes across its weekday and weekend schedule from February.
Claire Byrne will join Áine Lawlor presenting News at One on alternate days, with Claire continuing to presenting Claire Byrne Live on Monday nights on RTÉ One.
Late Debate, which airs from 10–11pm between Tuesday and Thursday, will have three new presenters, with Sarah McInerney on Tuesdays, Katie Hannon on Wednesdays and Fionnuala Sweeney on Thursdays.
Cormac O’hEadhra will take over Saturday with Claire Byrne programme and now present Saturday with Cormac O’hEadhra from 1-2pm weekly on RTÉ Radio 1.
"The new presenting team of Áine and Claire on RTÉ Radio 1’s News at One is exceptionally strong by any measure," said Head of RTÉ Radio 1, Tom McGuire.
"And the move of Cormac Ó hEadhra into weekend peak on RTÉ Radio 1 is testament to his proven skills both on RTÉ Raidió na Gaeltachta and standing in on such shows as Today with Sean O’Rourke.
"Sarah, Fionnuala and Katie - our three new presenters on Late Debate bring with them some truly excellent experience from the world of print, television and international journalism, and I’m delighted to welcome them all to Radio 1, and indeed to welcome Fionnuala Sweeney back to RTÉ from CNN."
All changes will take place in February 2018.
