Investigative journalist Roger Cook, widely recognized for pioneering the doorstep interview technique, has passed away peacefully following a brief illness, his family has confirmed.
"In addition to a distinguished and award-winning journalism career, Roger was first and foremost a cherished husband and father," their statement said.
"He will be profoundly missed by all of us, and we kindly request privacy as we navigate this challenging loss."
ITV, which aired The Cook Report during the 1980s and 1990s, led the tributes, commending Cook's "groundbreaking approach to investigative journalism," which it said "made him one of broadcasting's most trusted and respected figures."
He received a Bafta special award for "25 years of outstanding quality investigative reporting" for his namesake current affairs program, which aired from 1987 to 1999.
Cook "worked tirelessly to expose criminal wrongdoing and injustice, contributing to significant and lasting legal reforms," ITV stated.
"His fearless impact on journalism will be long remembered, and we extend our deepest sympathies and condolences to his wife, family, and friends during this difficult time."
Cook—born in New Zealand and raised in Australia—sustained bruises and beatings throughout his investigations, which focused on fighting injustice and advocating for crime victims.
During one doorstep encounter in 1981, he suffered three broken ribs at the hands of an alleged car thief wielding a baseball bat.
He relocated to the UK in the late 1960s, where his career progressed from BBC Radio 4—where he contributed to The World At One, the PM Programme, Checkpoint, and The World This Weekend—to 16 seasons of The Cook Report on ITV.
At its height, over 12 million viewers tuned in to watch the journalist's investigations.
And although he claimed to dislike it, Cook considered the Roger Cook doorstep approach essential.
At one point, police reported that a hitman had been hired to kill him.
Cook noted that audience research showed the public enjoyed seeing him take on crooks and fraudsters but didn't actually want to watch him being struck.
'What do you have to say to them?'
Cook's style of investigative journalism on radio and TV landed him in hospital roughly 30 times as he pursued various alleged criminals and con artists worldwide.
His work uncovered child abuse, Northern Ireland protection rackets, and baby trafficking in Brazil, along with the illegal ivory trade and the Russian black market for weapons-grade plutonium.
He also looked into illegal immigration, war criminals in Bosnia, and terror attacks, including those behind the September 11 attacks in New York City.
Speaking to fellow journalist Ruth Wishart on Life Behind the News, Cook explained that introducing a new, more confrontational reporting style had been necessary at the time and also matched his personality.
He said: "The Sunday Times did some pretty honorable work and some of the earlier World in Actions were quite good too—but they weren't confrontational.
"They didn't have a reporter that people could identify with going face-to-face against those individuals alleged to be responsible for whatever it was."
He added: "If you were just doing it for a newspaper, you might try to get your answers through a telephone call.
"I believe the best way to get answers, the way to best serve your contributors, the victims of these people, is to confront them.
"I don't mean confrontational in the sense of going in with all guns blazing. I mean actually standing in front of the person and saying, 'This is what you have done to the people in this program. What do you have to say to them?'"
Cook authored several books, including his autobiography, Dangerous Ground.
His bold and influential reporting style was frequently parodied by comedians such as Reeves and Mortimer, and Sir Stephen Fry.
