Meghan's father may not attend ceremony

Mr Markle told celebrity news website TMZ, at his home in Mexico, that he had decided not to attend his daughter's wedding to Prince Harry.

Kensington Palace issued a statement saying it was "a deeply personal moment for Ms Markle".

It follows Mail on Sunday reports that Ms Markle's father had staged pictures for a paparazzi photographer.

The widely circulated photographs showed him being measured for a wedding suit and looking at newspaper stories about his daughter.

Finding out dad isn't your biological father

Up to 3 per cent of people are the genetic offspring of someone other than the man they think, according to UNSW Professor Rob Brooks and Swinburne University of Technology Professor Michael Gilding, who have both studied misattributed paternity.

Possible scenarios include mum having multiple sexual partners at the time of the child's conception, undisclosed adoption, medical mistakes, the parents using a sperm donor to conceive or "dad" arriving on the scene when the child is too young to remember.

In some cases, dad may not even realise himself.
