PR Guru Nick, who has been Lord Sugar's right hand man on the series every episode so far, suggested that next year's tenth series could be the last.
The 69-year-old has worked alongside Lord Sugar for decades and claimed: "I wouldn’t be surprised if at some point after 10 years he said, ‘Actually lads, I think I’ve done my bit’.
“He is all over this show for 12 months of the year – every task, every aspect of the scheduling, marketing, and press.
“Don’t think he just pops in, does his little bit and pushes off home. Not a chance. He’s very devoted: Possibly, I think, to the detriment of his other business interests.”
But he added: "I’m only speculating, I’ve got no idea. He might say he’s only going to do 11 or 12 series, but then find it hard to walk away because it’s his baby.”
Speaking to the Radio Times this week, Nick said that the BBC would be "crackers" to continue on the show without Lord Sugar.
He explained: “If Alan Sugar says, ‘Look, I’ve done my 10 years,’ or whatever it is, I think they would be crackers to run it the next year with someone else.
“Rest it for three years, let the memories dim, and then bring it back. But somebody will say, ‘Are you mad? We want those eight million viewers,’ or whatever it is.
“It’s a huge show. Nobody wants to say cheerio to such a successful format.”
