1. The Arrest of Peter Mandelson (February 2026)

As of late February 2026, it is a matter of public record that Lord Peter Mandelson was arrested by the Metropolitan Police.

• The Charge: Suspicion of misconduct in public office.
• The Context: The investigation focuses on allegations that Mandelson shared market-sensitive and confidential government memos with Jeffrey Epstein during his time as Business Secretary (2008–2010).
• The Defense: Mandelson’s legal team at Mishcon de Reya has stated the arrest was “baseless” and claimed it was triggered by a false tip-off that he was a “flight risk” planning to move to the British Virgin Islands. He has been released on bail until May 2026.

2. The Arrest of Andrew Mountbatten-Windsor

In a historic move, the former Prince Andrew was also arrested on February 18, 2026, on suspicion of the same offense: misconduct in public office.

• The Evidence: New documents from the “Epstein Files” allegedly show Andrew forwarding confidential trade reports from his time as a UK trade envoy to Epstein.
• Status: He was released “under investigation” (RUI) after 11 hours of questioning. King Charles III issued a notable statement saying, “The law must take its course.”+1

3. Legal Analysis: “Misconduct in Public Office”

You correctly identified that the bar for this common law offense is exceptionally high. In the UK, it is not enough for an action to be “unpopular” or “controversial.”

• The Gap in the Video’s Logic: As you noted, “undermining public confidence” is a consequence of misconduct, but legally, the prosecution must prove wilful neglect or wilful misconduct that is so serious it amounts to an abuse of the public’s trust.
• The “Benefit” Rule: While the speaker in your reference suggests any “benefit” (even political) is enough, the law usually requires evidence of corruption or a specific quid pro quo (e.g., sharing secrets in exchange for money or favors).

Confirmed Legal Status (February 2026)

• The Arrest: Peter Mandelson was arrested on February 23, 2026, at his home in Camden. He was released on bail on February 24.
• The Charges: He is under investigation for misconduct in public office.
• The Evidence: The core of the police case rests on the “Epstein Files” released by the US Department of Justice in January 2026. These files contain emails from 2008–2010 (when Mandelson was Business Secretary) showing he allegedly shared:
  • A confidential Downing Street memo regarding a £20 billion state asset sale.
  • Insider information on the bankers’ bonus tax and a Euro bailout package before they were public.
• Other Arrests: Andrew Mountbatten-Windsor (the former Prince Andrew) was also arrested on February 18, 2026, on similar misconduct charges related to his time as a UK trade envoy.

2. Documentation on “The Stealing of Emily”

The http://www.stealingofemily.world run by Martin Newbold and the Stealing of Emily, documents a much wider series of allegations that connect these high-profile figures to systemic issues. According to the documents posted there in 2025 and early 2026:

• Matt Dunkley & Operation Dunham: The site highlights Dunkley’s history in the Victoria IBAC (Operation Dunham) investigation in Australia. It alleges that Dunkley was “extracted” from that investigation despite recordings suggesting he sanctioned the deletion of complaint documents.
• The Blair/Clinton Connection: The site claims that Tony Blair sought to redact information within the Clinton Library to hide a “framework” or “policy” related to the management—and alleged abduction—of children within the care system.
• Systemic Corruption: The platform argues that Mandelson, Blair, and Brown used their offices to protect individuals involved in children’s services scandals and that the current arrests for “misconduct” (over financial leaks) are only the tip of the iceberg compared to the alleged crimes involving the care system.

3. The “2009” Charges Connection

The reason the “2009” date is central to both the police and the activists is that it marks the peak of Mandelson’s power as “effectively Deputy Prime Minister” under Gordon Brown.

• Police view: 2009 is when the financial leaks to Epstein occurred.
• The site’s view: 2009–2010 is when the legislative and “secret court” frameworks (Closed Material Procedures) were allegedly being solidified to protect the state from the revelations documented on thestealingofemily.world.

Summary

While the Metropolitan Police are currently focusing on the misuse of government secrets (the Epstein emails), the documents you are referencing argue that the real misconduct involves a 20-year cover-up regarding child protection and institutional abuse.

As of today, the UK government is moving to strip Mandelson of his peerage, and the first tranche of “vetting documents” regarding his 2024 appointment as US Ambassador is expected to be released to Parliament in early March 2026. This may reveal exactly what the Cabinet Office knew about these historical ties before he was re-appointed.
