George Alagiah, one of the BBC's longest-serving and most respected journalists, has died at 67, nine years after being diagnosed with cancer.
A statement from his agent said he "died peacefully today, surrounded by his family and loved ones".
A fixture on British TV news for more than three decades, he presented the BBC News at Six for the past 20 years.
Before that, he was an award-winning foreign correspondent, reporting from countries ranging from Rwanda to Iraq.
He was diagnosed with stage four bowel cancer in 2014 and revealed in October 2022 that it had spread further.
Paying tribute, his agent said: "George was deeply loved by everybody who knew him, whether it was a friend, a colleague or a member of the public.
"He simply was a wonderful human being. My thoughts are with Fran, the boys and his wider family," she said.
Alagiah died earlier on Monday, but "fought until the bitter end", his agent added.
BBC director general Tim Davie said: "Across the BBC, we are all incredibly sad to hear the news about George. We are thinking of his family at this time.
"He was more than just an outstanding journalist, audiences could sense his kindness, empathy and wonderful humanity. He was loved by all and we will miss him enormously."
BBC World Affairs editor John Simpson tweeted: "A gentler, kinder, more insightful and braver friend and colleague it would be hard to find."
BBC chief international correspondent Lyse Doucet called him "a great broadcaster", a "kind colleague" and "a thoughtful journalist".
Clive Myrie, presenting the BBC News at One, said: "On a personal note, George touched all of us here in the newsroom, with his kindness and generosity, his warmth and good humour. We loved him here at BBC News, and I loved him as a mentor, colleague and friend."
After Alagiah's initial cancer diagnosis in 2014, the disease spread to his liver and lymph nodes, which needed chemotherapy and several operations, including one to remove most of his liver.
He said he was a "richer person" for the experience upon returning to presenting in 2015, and said working in the newsroom was "such an important part of keeping energised and motivated".
He had to take several further breaks from work to have treatment, and in January 2022 said he thought the cancer would "probably get me in the end", but that he still felt "very lucky".
Speaking on the Desperately Seeking Wisdom podcast in 2022, he said that when his cancer was first discovered, it took a while for him to understand what he "needed to do".
"I had to stop and say, 'Hang on a minute. If the full stop came now, would my life have been a failure?'
"And actually, when I look back and I looked at my journey... the family I had, the opportunities my family had, the great good fortune to bump into [Frances Robathan], who's now been my wife and lover for all these years, the kids that we brought up... it didn't feel like a failure."
Alagiah had two children with Frances.
