Ex-Prince Andrew allegedly viewed himself as a victim before he was arrested over his ties to convicted rapist Jeffrey Epstein.

“Andrew doesn’t know what the problem is,” royal expert Andrew Lownie exclusively told Page Six ahead of his shocking arrest Thursday.

“Andrew believes he’s been hard done by, he’s a victim in all of this, he’s being persecuted,” Lownie explained before noting, “He’s a narcissist and he’s never been disciplined.”

The author of “Entitled: The Rise and Fall of the House of York” had heard whispers of an investigation into Andrew’s alleged crimes before he was nabbed.

“I’ve heard he’s being investigated finally, seriously for sex trafficking and misconduct in public office,” Lownie said.

Andrew was ultimately arrested Thursday — on his 66th birthday — on suspicion of misconduct in public office for allegedly forwarding confidential trade documents to Epstein.

He could face life in prison if convicted.

The disgraced former royal was arrested just one month after anti-monarchy campaigner Graham Smith reported Andrew to the Thames Valley Police over alleged misconduct in public office.

According to newly released files, Andrew — who served as the UK’s special representative for international trade and investment between 2001 and 2011 — allegedly sent Epstein reports about trips to Vietnam and Singapore in 2010.

Notably, trade envoys must keep details about their trips confidential — even when they are no longer in the role — under the Official Secrets Act.

Authorities were also looking into allegations that a woman was trafficked to the UK by Epstein to have a sexual encounter with Andrew.

King Charles released a statement expressing his “deepest concern” over the accusations shortly after his brother’s arrest.

“I have learned with the deepest concern the news about Andrew Mountbatten-Windsor and suspicion of misconduct in public office,” he said in the statement issued by Buckingham Palace.

“What now follows is the full, fair and proper process by which this issue is investigated in the appropriate manner and by the appropriate authorities. In this, as I have said before, they have our full and wholehearted support and co-operation.”

“Let me state clearly: the law must take its course,” the monarch continued. “As this process continues, it would not be right for me to comment further on this matter. Meanwhile, my family and I will continue in our duty and service to you all.”

Page Six has learned that Prince William and Kate Middleton are in full support of Charles’ statement.
