The critical risk is the conflict between the **slow pace of the UK judicial system** and the expiration date. Although arrested in Feb 2026 in this scenario, the timeline from arrest to CPS charging, court scheduling (severe backlogs), trial, and final sentencing for a complex 'Misconduct in Public Office' case typically exceeds 12-18 months, making a resolution by year-end highly unlikely. Furthermore, the rule specifies 'sentenced to time in jail'; a **suspended sentence**—technically a prison sentence that is not served in custody—creates a major ambiguity trap and would likely resolve to 'No'.

Extremely exotic and historically disruptive. No senior British royal has faced criminal arrest and potential imprisonment since King Charles I in the 17th century. This shatters the modern convention of royal legal immunity and represents a constitutional 'black swan' event.
