King Charles is ready to “turn his back” on Prince Harry following the publication of his sensational memoir in January.
The King will be wished happy birthday by the Duke of Sussex on the day he turns 75, it has been reported.
Charles will be spending his birthday attending two royal events but at some point during the day his son Harry is expected to phone his father, according to an online BBC report.
Royal author Christopher Andersen claimed Charles “angers easily” and is “blindly devoted” to Queen Camilla.

He told Fox News: “My feeling is that Charles can so easily turn his back on Harry because Harry committed the one unforgivable sin: Harry dissed Camilla in his book, ‘Spare’ branding her a ‘villain’.
“He could have trashed [Prince] William and the monarchy all he wanted, but King Charles is wildly, blindly devoted to Queen Camilla.
“King Charles III angers easily, and he holds grudges.”
The King and his son have a strained relationship since Harry stepped down as a working royal and moved with wife Meghan and their family to America three years ago, for personal and financial freedom.
In a series of interviews since Harry left the monarchy the Sussexes have made a number of damaging accusations against the royal family.
Earlier this year, the Duke and Duchess of Sussex were asked to “vacate” their UK home just weeks after Harry’s damning book Spare was released.
Reports at the time claimed the move was sanctioned by the King and the decision removed their remaining foothold in the UK and further weakened ties with the royal family.
The King’s 75th birthday will be a working day for the monarch marked by gun salutes across the capital.
Charles will officially launch the Coronation Food Project with Camilla which aims to bridge the gap between food waste and food need.
The head of state and his wife will visit a surplus food distribution centre outside London and meet staff and volunteers to hear about the ways food waste can be used for social good.
Charles will also host a Buckingham Palace reception highlighting the work of nurses and midwives over the decades as part of the NHS 75 celebrations.
