Meghan’s sister launches another attack on her royal sibling

The Duchess of Sussex's half-sister has mounted another verbal attack against her famous sibling, claiming she has treated their father "coldly".

Samantha Markle, who has criticised Meghan a number of times since she was publicly linked with Harry, has been interviewed for a Channel 5 programme Meghan And The Markles: A Family At War.

Ms Markle tells the show, due for broadcast on Friday: "She doesn't have a heart or she would have been doing everything she could to make him comfortable and reciprocate, and be loving, and gracious and make sure he's comfortable in his old age."

She also says in the documentary: "I pointed out that humanitarians don't treat their father coldly, was that a lie, no, because the world watched it happen to my dad and the world watched her do it."

It is understood in the months leading up to the duke and duchess' wedding both Meghan, now heavily pregnant, and Harry tried to build bridges with Thomas Markle.

But the relationship appears to have broken down after he allegedly mocked up paparazzi photographs of himself.

And it may be irrevocably damaged by his actions in February when Mr Markle made public a handwritten letter from his daughter penned last year.

In the personal note the duchess asked her father: "If you love me, as you tell the press you do, please stop.

"Please allow us to live our lives in peace."

Meghan accused her father of breaking her heart "into a million pieces" by his actions.
