British Prime Minister Keir Starmer is reportedly preparing to announce his resignation, with UK media indicating he could step down as early as Monday, June 21.

The potential departure coincides with the swearing-in of his likely successor as a Member of Parliament, signaling a rapid transition within the ruling Labour Party.

Starmer has resisted calls for his resignation for months, but internal party dynamics and political pressure appear to have reached a tipping point.

The prospect of a leadership change in the UK’s largest economy introduces fresh uncertainty for markets already sensitive to political volatility.

Investors are closely monitoring the situation for signs of policy continuity or disruption, particularly regarding fiscal plans and regulatory frameworks.

A sudden change in leadership could delay legislative agendas and create short-term instability in government operations.
