Harry provides a glimpse of royal habits behind the partitions of royal residence as he describes life rising up as a member of the monarchy.

He reveals at Balmoral, the late Queen’s Scottish retreat the place the royal household spend their summers, guests could be left slightly involved by what got here out of the faucets.

The duke writes: “Brownish, suggestive of weak tea, the water typically alarmed visitors. Sorry, however there appears to be one thing incorrect with the water in my lavatory?

“Pa would at all times smile and guarantee them that nothing was incorrect with the water; quite the opposite it was filtered and sweetened by Scottish peat.”

Charles would come into the Balmoral bed room Harry shared together with his brother after they had been boys smelling of Eau Sauvage.

The duke writes in his guide Spare: “He’d slather the stuff on his cheeks, his neck, his shirt. Flowery with a success of one thing harsh, like pepper or gunpowder, it was made in Paris.”

It’s thought Charles wears Dior’s Eau Sauvage after-shave, which retails for round £74.

Harry passes judgement on what’s more likely to be his father’s longest serving companion – the teddy bear he took to Gordonstoun, the varsity the place the King was bullied as a boy.

Harry writes: “Teddy went in every single place with Pa. It was a  pitiful object, with damaged arms and dangly threads, holes patched up right here and there.”

He added: “Teddy expressed eloquently, higher than Pa ever may, the important loneliness of his childhood.”

The Duke of Edinburgh was famed for his love of barbecues he hosted throughout their Balmoral holidays, and even had a trailer particularly constructed to deal with all of the gear.

However his grandson Harry reveals Philip was a dab hand at making spaghetti bolognese on the coals, whereas for the Queen “Granny’s speciality was the salad dressing”.
