"But at the time, he might have been".
Harry and Meghan tried to keep things low-key, but, as usual, all eyes were on them.
He claimed Prince Harry is an interesting guy and when he expressed his dislike for Donald Trump, he told him to give Trump a chance.
"She would have asked him, and he would have said 'Yes, that's fine'". There was no real commitment for it.
In another conversation, Markle recalled getting an impression that Harry was "open to the experiment" of Britain leaving the European Union. The British royal family is famous for never publicly expressing their political beliefs.
Mr Markle was paid a "few thousand pounds" for the tell-all interview with Good Morning Britain and Meghan's father chose to do it because he wanted "set the record straight", host Piers Morgan revealed afterwards.
"It was incredible watching her", he said.
In an emotional moment, Thomas said, "The unfortunate thing for me now is that I'm a footnote in one of the greatest moments in history rather than the dad walking her down the aisle. So that upsets me somewhat".
Thomas went on to say he was "honoured" that Prince Charles walked his daughter down the aisle.
Mr Markle said he hopes he has not offended his daughter and her new husband for taking part in the interview.
He also spoke about his daughter's desire for children.
He also spoke of his series of phone calls with Prince Harry ahead of the wedding, in which he had asked for Meghan's hand in marriage. I was jealous, I wish I'd been there, I wish it'd been me, but thank God he was there. "Promise me you will never raise your hand against my daughter, and of course I give you my permission'".
The Duchess of Sussex confirmed two days before the wedding that her father would not be attending so he could "focus on his health".
Speaking about why he initially thought it was a good idea, Thomas told GMB's Piers Morgan and Susanna Reid: "This was a presentation to me, to change my image because in the a year ago photographs of me were always derogatory, so I thought this would be a nice way of improving my look".
"It's unprecedented, actually, for the queen to take such a new member of the royal family on the royal train", Nicholl said. "Meghan cried ... and they both said "take care of yourself, we're really anxious about you".
"So I thought this'd be an nice way of improving my look. I apologized for it", he said.
"Sadly, my father will not be attending our wedding". The royals are very complicated, but she can always rise to that occasion.
