Sean O'Rourke is set to fill the key 10am to 12 noon slot in the RTÉ Radio 1's schedule following the departure of Pat Kenny.

The News at One broadcaster, who is a multiple winner of the PPI News Journalist of the Year Award, is set to head up the flagship Today programme.

Speaking about his new position, 54-year-old O'Rourke said: “It’s 40 years ago next month since I began a lifelong love affair with journalism and I can honestly say I am as excited about this move as I was the first day I climbed the stairs in the Connacht Tribune in September 1973.

"I love radio and I love news. Friends and colleagues however will know me as a huge sports fan and an avid reader. Not only will we break news, drive the debate and analyse the stories of the day, we’ll be getting stuck into much more than that. I hope people will come for the news and stay for the craic. Here’s to September 2nd.”

O'Rourke also worked as a sports journalist and features writer for The Sunday Press and was a political correspondent for The Irish Press.

RTÉ today also announced that Aine Lawlor will present The Week in Politics on RTÉ One television.

Claire Byrne joins Morning Ireland as one of the core presenting team, and she will continue to present Saturday with Claire Byrne on Radio 1, and Prime Time on RTÉ One television.

Miriam O’Callaghan will continue to host the 9am to 10am slot on RTÉ Radio 1 and will also return to her senior presenter role on Prime Time in September. RTÉ also confirmed that John Murray will return in the coming months.

Aine Lawlor and Richard Crowley will alternate as presenters of RTÉ Radio 1’s News at One, with Lawlor also hosting The Week in Politics on RTÉ One television
