Bryan says he believes Andrew's denials of any wrongdoing.
"I believe Andrew is innocent. If he genuinely was involved in 'orgies', as has been alleged, then Epstein would have used that to try and bribe the Queen into paying out millions to protect her family.
"Andrew has never had any money. The Queen was the one with money.
"I truly believe Epstein was going after her but Andrew never gave him the ammunition to do so."
He claims he received a call from his former lover and Andrew's ex-wife, Sarah Ferguson, 10 days after the interview, asking him to come up with a strategic plan for dealing with its fallout.
"She invited me to come over. She was desperate. She told me that Andrew was in terrible shape," he said.
"He was distraught. They were distraught.
"In the four years I dated Sarah, I never once heard [Andrew] raise his voice or lose his temper," he said.
"It showed what strain he was under, how much he cared about the damage this was doing to the royal family."
