MEGHAN Markle is "an agent of poison" and "remorseless in her hatred", a royal expert has shockingly claimed.

Royal biographer Tom Bower claimed the Duchess of Sussex is ruthless once she decides someone "should be neutralised and destroyed".

The commentator, who is famous for his criticism of the Sussexes, sat down with Sun Royal Editor Matt Wilkinson on the Royal Exclusive Show.

He made some sharp remarks about his opinion on Meghan's fractured family relationships.

"Meghan is an agent of poison, she's able to destroy relationships and when she cultivates them it's always for her own good, her own purpose," Mr Bower claimed.
