No brotherly love here. A heated Prince William went to confront his brother Harry after the latter “slammed the phone down on him” over allegations Meghan Markle was bullying Palace staff members, according to a new French TV documentary about the once close brothers-turned-enemies.

RadarOnline.com has learned William allegedly called Harry to discuss the accusations about his bride, but the Duke of Sussex didn’t want to hear it. As a result, Harry hung up on his older brother, causing William to go into a tailspin.

[William] called Harry directly, and Harry slammed the phone down,” Pierrick Geais, a royal author who wrote a book about the second in line for King, alleged on Red Line: William and Harry, the enemy brothers.

“Harry didn’t want to know anything, and so William jumped in a car towards Kensington Palace, where he was going to confront Prince Harry.”

The documentary will be broadcast on August 30 — the 25th anniversary of Princess Diana’s death.

It will address the accusations brought against Meghan by the Sussexes’ former communications secretary, Jason Knauf in October 2018, in which he claimed the Duchess forced a few staff members to quit over her behavior and had undermined the confidence of another employee at Kensington Palace.

Knauf wrote the allegations in an email to William’s then private secretary Simon Case. The accusations against Meghan were brought to light in a report by The Times, just days before the Duke and Duchess of Sussex’s bombshell interview with Oprah Winfrey was set to air.

The program by the French channel BFM TV will also drop another bombshell never before told claim — those who left their positions due to Meghan’s alleged behavior started a WhatsApp group called “The Sussex Survivors’ Club.”
