A gambling watchdog is facing calls to investigate a surge of bets placed on John Healey being named Chancellor before the appointment was announced, after some wagers reportedly returned odds of 140/1. Critics say the pattern of betting suggests insider knowledge of the reshuffle may have leaked before it was made public, raising fresh questions about the security of Downing Street's decision-making process. Such episodes matter because they fuel suspicion that politically sensitive information is being exploited for financial gain, undermining public trust in the integrity of government appointments.

Concerns centre on the scale and timing of the wagers, which were placed at long odds shortly before Healey's shock elevation to the Chancellor role, prompting bookmakers and commentators to flag the activity as "suspicious". Calls have been made for the Gambling Commission to examine the bets and determine whether anyone with privileged access to reshuffle plans profited from advance knowledge, echoing similar controversies that have previously hit Westminster over leaked betting-market moves.
