Samantha Markle fought back tears as she discussed her dad's stroke with GB News' Dan.
Dan revealed yesterday that Mr Markle had suffered a major stroke, which has left him in hospital.
He also said Mr Markle has lost his speech and is currently receiving emergency treatment in the US.
Speaking exclusively on GB News' Dan Wootton Tonight, Ms Markle gave an update on her dad's condition.
She said: “He’s doing better, he’s in good spirits and it still hurts me to talk about it because he's been through so much.
“Two heart attacks, a pandemic and a stroke.
“I don’t think he saw it coming, I’m just so thankful to God that I called him when I did because he was slurring his speech, he couldn’t talk and I feel like If we hadn’t got emergency care right away it could’ve been fatal.
“I feel really blessed that he is getting some of his strength back and it’s going to take several, maybe six months, maybe a year to get his speech back.
“He can work with a speech therapist, the stroke he had in the speech production part.
“The stroke was in the right side of the brain so the damage was on the left and he’s left-handed but it also impaired his speech and his ability to swallow.”
Mr Markle exclusively told GB News last month that he was intending to travel to the UK for the Queen's Jubilee celebrations in the coming weeks.
But those plans will now not be happening following his health scare.
In an exclusive interview with GB News last month where he announced his plans to attend the jubilee, Mr Markle said he wants to meet and personally thank Prince Charles for walking his daughter Meghan down the aisle during her 2018 wedding to Prince Harry.
Mr Markle added: "I'm going to show my respects to the Queen, I'm going to make sure that the Queen understands that my entire family respects the Queen and the royals and we admire them."
