Earlier this week, the actor, writer and broadcaster confessed he had spent 'an enormous amount of money' on cocaine over a fifteen year period, which he writes about in his new autobiography, 'More Fool Me'.
In the book, his third life story, he admits he not only took the illegal drug at Buckingham Palace but also in the House Of Lords, the House Of Commons and BBC Television Centre.
He writes: “I take this opportunity to apologise unreservedly, to the owners, managers or representatives of the noble and ignoble premises and to the hundreds of private homes, offices, car dashboards, tables, mantelpieces and available polished surfaces that could so easily have been added to this list of shame.
“You may wish to have me struck off, banned, black-balled or in any other way punished for past crimes; surely now is the time to reach for the phone, the police or the club secretary.”
He goes on to reveal he spent 'hundreds of thousands of pounds' on cocaine at the height of his addiction.
“How can I explain the extraordinary waste of time and money that went into my 15-year habit?" he asks.
"Tens if not hundreds of thousands of pounds, and as many hours, sniffing, snorting and tooting away time that could have been employed writing, performing, thinking, exercising, living.”
He also admitted that he took the drug, not because he was unhappy, but simply because he 'really liked it'.
“I didn’t take coke because I was depressed or under pressure. I didn’t take it because I was unhappy (at least I don’t think so). I took it because I really, really liked it,” he writes.
