Thomas Markle has told how he cried as he watched his daughter’s wedding on television in a small rented hide-out, in a tell-all interview in which he claims Prince Harry was "open" to Brexit.

Mr Markle, who said he was “jealous” as the Prince of Wales walked his daughter down the aisle as he was receiving treatment for a heart attack, has spoken to Good Morning Britain in an extraordinary interview detailing private political conversations.

Claiming Prince Harry had once told him to “give Donald Trump a chance”, the 73-year-old alleged the sixth-in-line to the throne had seemed “open” to the idea of Brexit.

Mr Markle told how his daughter, then actress Meghan Markle, had confided in him that she had a new boyfriend, before eventually revealing he was British, then that he was a Prince they should call him “H” for security reasons.

He spoke to the Prince straight afterwards, he said, getting to know him over the telephone before giving his blessing to their marriage following their engagement in November.

“Meghan told me first and then a few times after that Harry got on the phone with her and asked for her hand over the phone,” he said.
