Writer Ms Levin, who has penned an authorised biography of Prince Harry, says Andrew had just three options to explore ahead of the civil case.
“We’ve seen that hasn’t worked – it hasn’t gone away. He thought it would all disappear into the night. It hasn’t.
“Remember how he was on Newsnight and then think of him on the stand, giving evidence.
“The second one was to go to America and answer all the questions and nit-pick apart the accusations, which is quite dangerous.
The Duke of York’s “car crash” Newsnight interview – in which he bizarrely claimed he doesn’t sweat – should warn him off giving evidence, Angela Levin says.
Speaking on talkRADIO this morning, Ms Levin said: “One was to ignore it, pretend it didn’t happen, he didn’t know anything about it.
“I think it would be a disaster for him.
“The third one is to try to worm out the fact that his accuser doesn’t have a case.”
