WILLIAM & HARRY FACE TO FACE AT BALMORAL!

After five years of feuding, the warring brothers are in for quite the showdown

- 

Prince Harry and King Charles have been taking steps to bridge their long estrangement, but by all accounts, a "stubborn" Prince William remains firmly against reuniting with his wayward brother.

The heir mightn't have any choice in the matter though, with their father pushing for a face to face between the warring brothers at Balmoral Castle, the Scottish summer home traditionally used for family summits!

"This is being orchestrated with the utmost of care and sensitivity because it's no secret that William is a reluctant party," a royal insider tells Woman's Day.

"It's taken months of discussion to convince him that there actually was an olive branch being offered by Harry, but now with this Balmoral summit looming, even William reluctantly acknowledges that if he's to be king to all his subjects one day, that does include his brother."
