British journalist David Frost, known for his cutting interviews with public figures including former President Richard Nixon, died suddenly on Saturday, according to reports. He was 74.

He gained international esteem following his 1977 interview of the disgraced president, during which his incisive questioning prompted an apology from Nixon over his role in the Watergate scandal. 

"I let the American people down and I have to carry that burden with me for the rest of my life,” Nixon said.

He said: "I'm sorry."

The exchanges were dramatized in the 2008 film, "Frost/Nixon."

Frost died of a suspected heart attack Saturday night abord a cruise ship, according to the Associated Press.

Frost led a long and broad career, sitting down with seven U.S. presidents and six British prime ministers throughout his 50 years in journalism. 

He also engaged in lighter interviews with celebrity figures, and launched a number of satirical British news and sketch shows early on in his career.

Since 2006, Frost had conducted interviews for Al Jazeera English. Actor George Clooney and former defense secretary Donald Rumsfeld were among his guests.

In one 2006 interview for Al Jazeera English, then-British Prime Minister Tony Blair agreed with Frost that the Iraq war had "been pretty much of a disaster," until that point.
