Dobson joined the national broadcaster in 1987, and presented all of RTÉ's flagship news programmes across television and radio, including anchoring coverage of elections and special State events.

"RTÉ journalism depends on teamwork and I have worked with some of the very best.
"I am grateful too to the listeners and viewers who have give me their time and attention over the years. I hope to have repaid that trust with reporting that was relevant, fair and accurate."
RTÉ's director general Kevin Bakhurst said Dobson "represents the best in public service journalism".
"For many years, he has brought a calm authority to the most important stories. Every day, he demonstrates a depth of knowledge, and an absolute integrity in his work and has never been afraid to ask the toughest questions and hold the powerful to account.
"Personally, it has been a pleasure and a privilege to work with him," Mr Bakhurst added.
Dobson joined the broadcaster in 1987 as a reporter with RTÉ Radio 1's This Week programme. Later that year, he was appointed as RTÉ's business correspondent, and presented business programme Marketplace.
In 1991, he became presenter of One O’Clock News, later moving to present the Nine O'Clock News, before going on to anchor the Six One News in 1996.
He spent 21 years at the flagship programme, before moving on to become part of Morning Ireland's presenting team in 2017.
