In his six-page Instagram statement in January, Brooklyn made clear that relations with his parents had broken down, saying he had been forced to respond after they had “continued to go to the press”.

He made claims including that his mother had “cancelled making Nicola’s [wedding] dress at the eleventh hour” and “danced very inappropriately on me in front of everyone” during the ceremony.

He also claimed his family values “public promotion and endorsements above all else”, adding that “family ‘love’ is decided by how much you post on social media, or how quickly you drop everything to show up and pose for a family photo opp”.

The events of the wedding have been disputed by some guests. DJ Fat Tony backed up Brooklyn’s claim about the “awkward dance” with his mother, but singer Marc Anthony said the way events had been presented was “hardly the truth”.

Sir David has not commented directly, but speaking generally about social media at a panel in Davos shortly after Booklyn’s statement, he said children are “allowed to make mistakes”.
