Ahead of the new series starting, Len has spoke out about stepping down from the BBC One series after a decade.
Len confirmed last year he was quitting Strictly and the 2016 series would be his last.
In an interview with the Daily Mirror newspaper, Len said leaving was the "right thing" to do.
He explained "I’ll be sitting at home with my old Sue saying, 'I could have been there now doing this. Why didn’t I do it?' But I know it was the right thing to do.
"I’m 73, you can easily start to get a bit dithery and I’d hate that.
"It’s much nicer to go and have everyone say, 'Ah, shame you’re going Len, what a pity, we’ll miss you,' than, 'Thank God that old geezer is leaving,'" he says.
Len went on to say he found it "tough" flying between his job on the UK show and the US version, Dancing With The Stars.
"They fly us first class, but you could be on a private jet, you’ve still got an eight-hour time difference to cope with. It’s a real hard schedule. I don’t know how I did it. Probably greed…" he said.
Len went on "Talking of Strictly . Do you think they’ll keep Len’s Lens, as a tradition? Wouldn’t that be lovely?
"It’d be like the Strictly equivalent of a blue plaque, an homage to dear old Len."
Meanwhile, Len heaped praise on his replacement, Shirley Ballas.
"I’ve judged her at thousands of competitions and I taught her and her husband Corky, and there’s no one who knows their ballroom and Latin like her," Len raved. "Fantastic, wonderful dancer, far better than I ever was."
The new series of Strictly Come Dancing will start on BBC One in September.
