AWARD-winning RTÉ journalist Keelin Shanley has been remembered as an "exceptional broadcaster and a wonderful colleague".
Tributes have flooded in to the Six One News presenter, who died at her home in Dublin on Saturday aged 51.
She had been battling cancer for a number of years.
Ms Shanley had worked across an array of RTÉ news and current affairs programmes.
She made several acclaimed documentaries, many of which focused on social issues and gave voice to people on the margins of society, including the homeless and those affected by health inequality and drug abuse.
She also reported from developing countries including on the plight of child soldiers in the Lord's Resistance Army in Uganda and the rebuilding of Liberia.
RTÉ news and current affairs managing director Jon Williams said she was "the best of us - and we are heartbroken".
"From Prime Time Investigates to Morning Edition, Morning Ireland to the Six One News, there wasn't a corner of RTÉ News & Current Affairs untouched by Keelin's fearless, generous, and passionate journalism.
"For Keelin, the story was never about her - always about others. Her legacy of over 20 years' journalism with RTÉ saw her help tell the stories of so many often marginalised. She strove to inform, probe and encourage. Always inquisitive, interested, thoughtful and kind.
"The fact that she presented our flagship Six One News while dealing with cancer is inspirational in itself and so typical of Keelin's determination to live life to the full."
President Michael D Higgins said Ms Shanley was "driven by a strong commitment to social justice" and "brought great professionalism and dedication to her work as a journalist".
Fianna Fáil leader Micheal Martin said she was "always very warm and engaging in person and incisive and endlessly professional in her journalism", while Sinn Féin president Mary Lou McDonald said she will be remembered as a journalist "of great integrity and talent".
Among the many colleagues who paid tribute was Morning Ireland presenter Rachael English, who said: "Keelin was a wonderful journalist but she was also a fantastic, generous, funny colleague. She'll be missed so much. Sympathies to her family and friends. May she rest in peace."
Ms Shanley is survived by her husband Conor and their children Lucy and Ben.
