Cabinet ministers have reportedly shifted their belief from Andy Burnham bluffing about a return to the EU to serious consideration, following the appointment of Ben Nunn as the Prime Minister's EU adviser. Nunn previously served as a senior advisor to Keir Starmer and chief of staff to Rachel Reeves.

One minister, speaking anonymously, suggested that Nunn's role is to "mastermind the Rejoin campaign," highlighting his reputation as a "skillful, if combative, political strategist" within Westminster circles. While not a foreign policy specialist, Nunn is credited with assisting in election victories and managing media for Reeves.

Sources indicate that Burnham has been seeking Nunn's expertise for weeks, with support from Cabinet Office minister Lou Haigh. Initially, some believed Burnham's pro-European stance was posturing to appease the Labour left ahead of an anticipated general election. However, Nunn's appointment suggests a potential move towards restructuring Britain's relationship with the EU.

The development coincides with Rachel Reeves publicly stating that "Britain's future lies in the European Union." This coordinated messaging has led to speculation that Reeves may be positioning herself for a significant role in a future referendum campaign. This prospect, however, has drawn concern from some Labour colleagues, particularly those in swing seats, who fear that reopening Brexit arguments could benefit the Reform party.

Despite internal concerns, the Prime Minister's actions, exemplified by Nunn's appointment, indicate a serious consideration of a closer relationship with the EU and the possibility of a second referendum, suggesting the government is not merely engaging in political maneuvering.
