A Conservative think-tank has been knocked back after trying to bid for access to the Duke of Sussex's US visa application, it has been claimed.

Taking to X, TalkTV tweeted: "A Conservative think tank has failed in its bid to gain access to the Duke of Sussex’s US visa application after questioning why he was allowed into the country following references to taking drugs in his memoir, court documents show."

In his memoir, Harry admits to extensive use of cocaine, marijuana and magic mushrooms. The 40-year-old wrote: "I'd experimented with them over the years, for fun, but now I'd begun to use them therapeutically."

Speaking of cocaine, he wrote: "It wasn't much fun, and it didn't make me particularly happy, as it seemed to make everyone around me, but it did make me feel different, and that was the main goal."

As reported by GB News, US judge Carl Nichols said that "the public does not have a strong interest in disclosure of the duke’s immigration records".

The judgment added: "Like any foreign national, the duke has a legitimate privacy interest in his immigration status."

The lawsuit was brought by The Heritage Foundation against the Department for Homeland Security (DHS) after a Freedom of Information Act request was rejected. The think tank claimed that it was of "immense public interest".

However, Judge Nichols has said that the public’s interest in the Duke of Sussex’s immigration records is "outweighed by the duke’s privacy interest".

Speaking of Harry, the judge said: "Public disclosure of records about a single admission of a foreign national in the circumstances described above would provide the public, at best, limited information about the department’s general policy in admitting aliens.
