Harry, William argue during Prince Philip's funeral

British historian and biographer Robert Lacey has said that Prince William hates younger brother Prince Harry's wife, Meghan Markle, and that it was because of her that the two brothers had quarreled at the funeral of their grandfather, Prince Philip, according to The Daily Mail.

As per Lacey, the conflict between William and Harry had started about three years ago, but during Prince Philip's funeral, the acquaintances of the two princes had expressed hope that the brothers would be reconciled.

But despite their calm behavior during the funeral, the conflict between the brothers had continued outside Canterbury Cathedral.

“There they were, at each other's throats as fiercely as ever,”  an eyewitness had told Lacey

The insider points to Meghan  as the culprit of the dispute between William and Harry.
