A dramatic new chapter is unfolding inside Buckingham Palace as reports suggest King Charles III has granted police access to all files and records relating to his younger brother, Andrew Mountbatten-Windsor.

According to sources cited by The Observer, the decision was made despite concerns from some royal staff that the documents could expose uncomfortable truths — including whether senior palace figures were aware of Andrew’s alleged conduct over a prolonged period. One source warned investigators may now have scope to “follow the evidence” wherever it leads.

In a public statement following Andrew’s arrest on suspicion of misconduct in public office, the King made his position clear. He said he had learned of the news “with the deepest concern” and stressed that “the law must take its course.” He added that the police have his “full and wholehearted support and co-operation.”

Authorities confirmed that searches have continued at Royal Lodge, Andrew’s former residence, with officers reportedly seen arriving in unmarked vehicles. Thames Valley Police said they have opened an investigation into allegations that Andrew shared sensitive information with the late sex offender Jeffrey Epstein while serving as the UK’s trade envoy.

The latest developments follow the release of additional US Department of Justice files connected to Epstein. Both Andrew and his former wife, Sarah Ferguson, appear in correspondence contained within those documents.

Andrew has consistently denied any wrongdoing. As scrutiny intensifies, questions now focus not only on the allegations themselves, but on what palace records may reveal — and how this unprecedented cooperation could reshape the monarchy’s response to one of its most serious crises in modern times.
