Meghan's brother writes to Prince Harry: Wedding ‘biggest mistake’ in royal history

Meghan Markle’s estranged half-brother has shared a handwritten letter telling Prince Harry it's 'not too late' to cancel the wedding to his sister.

Meghan’s elder sibling Thomas Markle Jr warned Prince Harry to ditch May 19 union with actress insisting that the 36-year-old is a 'jaded, shallow, conceited woman that will make a joke of you and the royal family heritage.'

The letter, that was shared with In Touch magazine reads, “As more time passes to your royal wedding, it became very clear that this is the biggest mistake in royal wedding history.”

He further added, “Meghan Markle is obviously not the right woman for you. I'm confused why you don't see the real Meghan that the whole world now sees. Meghan's attempt to act the part of a princess like a below C average Hollywood actress is getting old.”

The 51-year-old, who is from Oregon in the US, then went on to claim that their father went into debt in order to support Markle's acting dream and is still struggling financially.

He also claims that their father was not invited to the wedding.

Markle’s elder brother added in the letter, “'What kind of person starts out by using her own father until he's bankrupt, then forgets about him in Mexico leaving him broke, over mostly all her debts.”

According to Thomas, Meghan conveniently forgot about her father when it was time to pay him back.

The letter further reads, “Not to mention, to top it all off, she doesn't invite her own family and instead invites complete strangers to the wedding. Who does that? You and the royal family should put an end to this fake fairytale wedding before it's too late.”

Thoams Markle finished with: 'Meghan is still my sister. She is family. So whatever happens is up to her, whether she wants to forget knowing me or the rest of her family, family comes first. Also, you would think that a royal wedding would bring a torn family closer together, but I guess we're all distant family to Meg.”

Meghan's half-brother has previously hit out at his sibling after revealing that her royal wedding snub has 'torn the family apart'.

Thomas has not seen his sister since 2011 when the pair – and Meghan's film producer ex Trevor Engleson, 41 – attended the Los Angeles funeral of their grandmother, Doris.

Markle believes that his brushes with the law may have embarrassed his half sister who is avoiding him.
