Brendan O'Connor is to be the new presenter of the weekend radio slot held by Marian Finucane until her death last month.
Starting in mid-March, O'Connor will present a two-hour programme on RTE Radio 1 from 11am-1pm on Saturdays and Sundays.
O'Connor, who had been a frequent stand-in presenter for Finucane, will continue to write for the Sunday Independent and Independent.ie.
However, O'Connor will leave his role with the newspaper as deputy editor (features) and Life magazine editor.
"After 15 years working in the Sunday Independent, I'm delighted to be joining the weekends on RTE Radio 1," he said.
"The weekend is a time to pause, take a breath and review the week, and it's also a time when people like a different, more reflective kind of radio, maybe even a bit of fun.
"Marian's legacy will inspire us to continue to explore, challenge and debate the issues that truly matter to Irish people.
"I'm looking forward to developing an informative, sparky, original and unpredictable show.
"I want this to be robust and enjoyable radio, always questioning and always seeking insight."
Tom McGuire, head of RTE Radio 1, said: "The death of Marian Finucane has created a void in Radio 1 that cannot be filled.
"Radio 1 has taken time to reflect on the weekend schedule and I'm really pleased that Brendan O'Connor is joining us from the Sunday Independent to present the weekend mid-morning show.
"Brendan is a talented broadcaster who will bring his own special skills to the role and I'm sure the large audience will welcome the new programme we will present at this time."
Meanwhile, Independent News and Media publisher Peter Vandermeersch said: "We would like to thank Brendan for his incredible work for - and dedication to - the Sunday Independent over 25 years."
O'Connor has appeared on and presented several hit shows for RTE.
