On Tuesday, Mr Morgan stormed off the set of Good Morning Britain altogether after clashing with the show’s weather presenter, Alex Beresford, about the Winfrey interview.
Both the Duke and Duchess also claimed they approached people in the royal “institution” for help but were turned away.
While some recollections may vary, they are taken very seriously and will be addressed by the family privately.
An Ofcom spokesperson said: “We have launched an investigation into Monday’s episode of Good Morning Britain under our harm and offence rules.”
