Meghan Markle's father will not walk the Royal bride down the aisle, after he pulled out of his daughter's wedding to Prince Harry.

Thomas Markle, 73, said he would no longer be flying to Britain, after embarrassing disclosures about his dealings with the paparazzi.

Mr Markle reportedly told the US showbusiness website TMZ that he had suffered a heart attack six days ago, but had checked himself out of hospital and had been intending to travel for the ceremony on Saturday.

But he will no longer make the journey to meet his future son-in-law Prince Harry, he said, or keep appointments with the Queen, Prince Philip, Prince of Wales, Duchess of Cornwall and Duke and Duchess of Cambridge.

The decision leaves arrangements for the Royal wedding in doubt, and Ms Markle without her father on the biggest day of her life.

It also raises the question that her mother, Doria Ragland, may walk her down the aisle, or that she will be accompanied by a member of the Royal family or make the journey alone.
