In 2013 he revealed he was battling bowel cancer and feared he would never meet his grandson, Angelo — Adele’s son with charity entrepreneur Simon Konecki, who she divorced in March.

But Mark went on to claim that her third album, 25, released in 2015, had proved to be a cathartic period in their relationship and that they had patched up their dispute.

He even called the feud a “misunderstanding”.

However, Adele countered this in a speech at the 2017 Grammy Awards. She told the audience: “Thank you to my manager because the comeback, as it were, was completely masterminded by him.

“And you executed it incredibly, and I owe you everything. We’ve been together for ten years, and I love you like you’re my dad. I love you so, so much. I don’t love my dad, that’s the thing. That doesn’t mean a lot. I love you like I would love my dad.”

In 2011 Mark admitted to The Sun that his boozing had “made Oliver Reed look like a teetotaler”.

He confessed: “I was a rotten father at a time when she really needed me. “I was putting away two liters of vodka and seven or eight pints of Stella every day. I drank like that for three years. God only knows how I survived it.”
