Martina Fitzgerald is leaving RTÉ News and Current Affairs after 18 years.

During her time in RTÉ, she worked across a number of flagship programmes, including Morning Ireland and the Six One News.

Ms Fitzgerald formed a central part of RTÉ's political coverage over the last five years, working as a political correspondent based in Leinster House.

During that period she covered a number of significant referendums, including those on same-sex marriage and abortion.

She also worked on RTÉ coverage of several elections, as well as numerous other political matters.

In a statement, Ms Fitzgerald said she is leaving "for new professional adventures".

She said: "I take great pride in my work reporting from Leinster House as RTE’s Political Correspondent and especially covering the dramatic 2016 general election and subsequent prolonged government formation process as well as the historic referendums on Marriage Equality and the Eighth Amendment. 

"I loved every minute reporting on political developments - and providing analysis and context - for RTÉ’s audience.

"Thank you to my colleagues who helped me with all this work and to everyone for their loyalty and decency."

Managing Director of RTÉ News and Current Affairs, Jon Williams, wished Ms Fitzgerald "every success in her future endeavours".

Ms Fitzgerald also recently wrote a book, 'Madam Politician', on the experiences of female politicians in Leinster House.

Earlier this month Paul Cunningham was appointed as one of RTÉ News' two political correspondents.
