Letter: Meghan Markle's half-brother lives in Oregon, asks Prince Harry to cancel wedding

Meghan Markle’s estranged half-brother, who lives in Grants Pass, Oregon, wrote a letter to Prince Harry encouraging him to call off the royal wedding, according to In Touch Weekly.

Thomas Markle Jr., who has the same father as Meghan Markle, wrote a handwritten letter to the prince saying it’s “not to [sic] late” to not marry his sister.

Thomas Markle Jr. shared the letter exclusively with In Touch.

“As more time passes to your royal wedding, it became very clear that this is the biggest mistake in royal wedding history,” Thomas Markle Jr. wrote.

He goes on to accuse Meghan Markle of driving their father into bankruptcy and leaving him broke in Mexico.

He says Meghan Markle will “make a joke out of you and the royal family heritage.”

Thomas Markle Jr. says his half-sister did not invite their father to the wedding.

However, according to People, Meghan’s father Thomas Markle plans to attend the wedding at Windsor Castle’s St. George’s Chapel.
