Kevin Bakhurst joined the state broadcaster four years ago
The head of RTÉ News and Current Affairs is to leave the organisation in October.
Kevin Bakhurst joined the state broadcaster four years ago as managing director of the division, and was later appointed deputy director-general.
He was most recently acting director-general, following the departure of Noel Curran.
"It has been an absolute privilege to work for the national broadcaster during a time of change and renewal and I wish Dee Forbes and the whole organisation the very best for the years to come," Bakhurst says.
RTÉ Director-General Dee Forbes added: "Kevin Bakhurst has led RTÉ News and Current Affairs decisively through a period of intense change and development, and his contribution, inside the newsroom, and beyond, has been significant."
"I’d like to warmly congratulate Kevin on this new role and wish him the very best for the future."
Bakhurst will take up a new position as content group director for Ofcom, the communications regulator in the UK.
RTÉ says a competition to appoint his replacement will be announced in due course.
