UK government bonds rallied and the pound sterling strengthened against major currencies on Monday following the announcement that Prime Minister Keir Starmer has resigned.

The move confirms reports that had circulated over the weekend regarding his imminent departure from Downing Street, ending his tenure as head of government and leader of the Labour Party.

The immediate market reaction suggests investors are interpreting the leadership change as a catalyst for potential policy shifts.

Gilts saw buying interest as traders reassessed the fiscal outlook under a new Labour leadership, while the currency firmness indicates a bid for stability or a repricing of political risk.

The development marks a sudden shift in the UK's political landscape, with the resignation announced on Monday morning.

Starmer's departure leaves the Labour Party and the UK government in a transitional phase.
