Sir David Frost, who died this morning, will go down in history as one of the greatest interviewers and journalists of his generation – perhaps of all time. His laconic style hid a forensic brain, determined to get to the truth. He didn’t believe in confrontation as a form of interview, he didn’t believe in constant interruption. He believed that if you let your interviewee talk, they might just say something of interest and not put the shutters up. Kay Burley said this morning that he believed the best three questions and interviewer has at his or disposal are “Ah”, “Really?” and “Oh, do go on”. I think he had a point.

Sir David was a risk taker and an innovator. He was as comfortable interviewing Hollywood celebrities as he was prime ministers and presidents. He could host a game show, turn his hand to satire and then the next day present an election programme.

I first got to know Sir David when he would come into Politico’s, buy a few books and want to have a gossip over the counter. He had no airs and graces. He felt a friend from the first minute you met him, and there aren’t many people who can achieve that. I then reviewed the papers a couple of times on ‘Breakfast With Frost’. The first time, I was incredibly nervous. It was the biggest TV programme I had been on at that point, and it was the weekend before the Iraq war started. I was on with Polly Toynbee and Trigger from Only Fools & Horses. As we sat down on the sofa, he leaned over, touched my knee and winked. He said nothing, but that one, thoughtful act did more than any words ever could to calm my nerves. The next time I was on, it was with Helena Kennedy. The programme started at 9, but at 8.45 there was no sign of Sir David. No one seemed to be remotely concerned. Sure enough, five minutes later he arrived looking, it has to be said, rather out of it. But as soon as the red light went on it was “Hello, good morning and welcome” and off we went. He was the ultimate showman.

In 100 years time there is little doubt that his enduring legacy will be the Nixon interviews. He gambled everything, including his own personal fortune, on those interviews. The fact that they were turned into a theatre show and then a movie tells us all we need to know about their historical importance.

Let me leave you with two personal memories. One came early on in my days at LBC. I wish I could remember what it was about, but I found myself interviewing Sir David about something or other. I started by feeling very intimidated, but he immediately put me right at my ease – when it should have been the other way around. And then a few months later I got an email from him (I’ve tried to find it, but can’t). He said he often listened to my programme in the car (he used to present on LBC) and he had liked an interview I’d done the previous night. I could not have been more proud.

I won’t pretend he was a close personal friend, but I can truly say I am proud to have known him.

His interviewing skills are really on show in this 1969 interview with Enoch Powell
