Meghan Markle's father Thomas has suffered a major stroke, and lost his speech, according to reports.
Kiwi journalist Dan Wootton has reported Markle, 77, is receiving "urgent medical treatment in an American hospital".
"I am devastated to report this news, just seven days before Thomas would have joined me in London to celebrate the Queen's 70th year on the throne for a TV special on my GB News show, fulfilling his long-held wish to visit Windsor Castle," Wootton wrote in the Daily Mail.
"I have been aware of the stroke since this morning and had agreed with both Thomas and his distraught daughter Samantha not to report the news while he underwent further tests to establish the severity of the stroke.
"But a high-profile American website has received information from within the hospital, meaning news of his stroke was about to break."
