Sir Elton John’s mother wanted to stop his civil partnership from going ahead because she was jealous of his relationship with David Furnish.

The 72-year-old singer and filmmaker David Furnish were the first same-sex couple in the UK to have their union made official in December 2005 but the “Rocket Man” hitmaker was worried throughout the big day because his mother Sheila – who he claimed often had irrational outbursts of rage – was as disruptive as possible and he only found out why later.

Writing in his memoir “Me”, which is being serialised by the Daily Mail newspaper, he recalled: “I didn’t find out what had provoked all this until much later. It turned out that David’s parents, who are Canadian, had known what the problem was all along, but hadn’t wanted to upset us.

“They’d rung Mum as soon as they arrived in the UK. They always got on well with her and Derf. They’d even been on holidays together.

“My mother told them they all had to work together to stop the civil partnership going ahead. She didn’t approve of two men ‘getting married’, as she put it.
