The Oscar winner would happily portray Jackson Lamb for “the rest of my career” but says keeping podgy for the role could mean issues in the future.

The 67-year-old adores the part he has played for five years - and which earned him an Emmy nomination for outstanding lead actor in a drama series.

However, the star, who wore a fat suit for Darkest Hour to play Sir Winston Churchill - earning an Oscar - has gone method for the M15 reject.

Sir Gary confessed: “I will tell you, it is five seasons and it’s murderous.

“You know what, it’s French fries and hot dogs and hamburgers and ice cream. It’s disgusting, isn't it?”

He added: “Here’s the problem: it’s not that I blow up in between gigs, it’s just I eat well. At 67, it’s very hard to lose it.”
