How Meghan Markle's sister Samantha Markle is threatening to ruin royal baby birth

Meghan Markle's family seem determined to spoil her reputation, continuously coming out with negative claims in an effort to change the way the world sees her.

The latest attempt is from Markle's older half-sister Samantha who has announced she will release not one but two tell-all books about the Duchess, to coincide with the birth of the royal baby.

In November, Markle's half-sister announced she'd be releasing a book dedicated to her "social climbing" sister she's coined "Princess Pushy".

In anticipation of the royal baby's April arrival, the 54-year-old appears to have dragged up more tales, announcing she will be releasing a second title.

The first book has been through a series of name changes: "The Diary of Princess Pushy's Sister", was changed to "A Tale of Two Sisters". The latest title appears to be "In the Shadows of the Duchess".

Hyping the release, she's tweeted that the books are a "sociological journey" and: "the world does not know (the) truth … (I'm) holding nothing back!

The wheelchair-bound American has previously travelled to the UK in the hopes of meeting with the Duchess. And she has appeared in televised interviews attacking her younger sister's behaviour, among other attempts to bring her down.

Markle's father and brother also appear determined to damage her reputation.

Thomas Markle's most recent ploy was sharing private information about his daughter, such as intimate details from her first wedding.
