Duke of Sussex's visa records will remain a secret despite his past drug use, after a Conservative think tank lost a lawsuit.

Prince Harry may have gone public with his drug taking in his best-selling memoir, but his U.S. visa application will remain private, a judge has decided.U.S. District Court Judge Carl Nichols on Monday knocked back a lawsuit from the Heritage Foundation trying to force the government to release the exiled royal’s application to check if there was any mention of drug use.

The conservative think tank argued the public had an interest in how the Department of Homeland Security handled Harry’s application given his past drug use.
