Meghan Markle's brother says it is not 'too late' to call off the wedding in letter to Prince Harry

Soon-to-be Royal bride has not seen her half-brother since 2011

There is one person who isn’t excited for the upcoming royal wedding between Prince Harry and Meghan Markle - her own brother.

In a handwritten letter addressed to Prince Harry, Markle's estranged half-brother, Thomas Markle Jr, criticised his sister and warned Prince Harry it is not "too late" to call off the wedding.

In the letter shared with In Touch magazine, the 51-year-old wrote: “As more time passes to your royal wedding, it became very clear that this is the biggest mistake in royal wedding history.”

Markle’s older brother then goes on to criticise Markle’s relationship with their father, who Thomas claims helped Markle with money.

According to Thomas, who has not seen his half-sister since 2011, it was the fact that the American actress did not invite her family to her upcoming royal wedding, instead inviting “complete strangers,” that struck a nerve with her half-brother, who asked: “Who does that?”

In the letter, Thomas blames Hollywood fame for allegedly changing Markle, who starred on Suits until recently.

“It’s very apparent that her tiny bit of Hollywood fame has gone to her head, changing her into a jaded, shallow, conceited woman that will make a joke of you and the royal family heritage,” he wrote.

Concluding his letter, Thomas accuses Markle of keeping their “torn family” apart by not inviting them to the royal wedding, but admits that Markle is “still my sister.”

This isn’t the first time Markle’s half-brother has spoken out against his sister.

Last month, Thomas told the Daily Mirror that Markle has “forgotten her roots” and likes to portray herself as a “people’s person.”

He said: “She is giving the greatest performance of her life. She is acting phoney. Once she got into Hollywood she turned into a different person. She’s clearly forgotten her roots and her family.”

But Thomas insists he is not hurt over not being invited to the upcoming wedding on 19 May 2018.

“I’m not bitter, just baffled,” he told The Mirror. “It’s hurtful given how close we once were.”
