Prince Harry claims Prince William physically attacked him during argument about Meghan

Prince Harry has claimed that his brother physically attacked him during an argument about his wife Meghan.

It's just one allegation from Harry's memoir 'Spare', which went on sale unexpectedly in Spain today, five days before its official launch date.

According to newspaper reports, other claims in the book include Harry admitting to taking cocaine, how he asked his father not to marry Camilla, and claiming that he killed 25 people during his time in Afghanistan with the army.
