Allegedly, Prince William can display a fiery temper behind palace doors despite his calm and polished public image.
The future king is often described as charming, patient and approachable during royal engagements. However, fresh claims suggest his behaviour in private can be very different, especially around King Charles III.

Prince Williamâs alleged outbursts behind closed doors
Royal author Christopher Andersen discussed Williamâs reported temper in his book Kate! The Courage, Grace, and Power of the Woman Who Will Be Queen.
Speaking to Page Six, Andersen claimed: âWilliam is capable of great bellowing tantrums.â
The author added that while William is said to be âkind and considerate to a faultâ around Kate Middleton and their children, things can allegedly change when tensions rise elsewhere.
A former staff member at Highgrove reportedly claimed William has been known to raise his voice when frustrated.
âWilliam has a huge, booming voice,â the former aide alleged. âMuch louder than his fatherâs, so itâs not something you soon forget.â
Andersen also claimed William may have inherited his temper from Charles, who has long been rumoured to have a fiery streak of his own.
The author previously alleged the king once became so angry after losing a cufflink down a drain that he tore âa sink off the wallâ.

Prince Harryâs claims about Williamâs temper
Prince Harry also made explosive allegations about his brotherâs temper in his memoir Spare.
Harry described an alleged confrontation at his London home in 2019, claiming William arrived angry during an argument about Meghan Markle.
According to Harry, the situation escalated into a physical altercation.
The Duke of Sussex claimed William had a âpiping hotâ temper before allegedly grabbing him by the collar and throwing him to the floor.
Harry wrote that he landed on a dog bowl which âcracked under my back, the pieces cutting into me.â
âWilly, I canât speak to you when youâre like this,â Harry claimed he told his brother before fetching him a glass of water.
The argument allegedly continued moments later.
âHe grabbed me by the collar, ripping my necklace and he knocked me to the floor,â Harry wrote.
According to the duke, William later appeared regretful and apologised before telling him: âYou donât need to tell Meg about this.â
Kensington Palace and Buckingham Palace have reportedly been contacted for comment.
