According to TD Securities analysts James Rossiter and Julie Ioffe, UK Prime Minister Starmer is expected to be replaced by late September, with the Labour Party's leadership contest likely to begin in late June. The main contenders for leadership are Burnham, Streeting, Rayner, and Miliband, and the party is anticipated to shift leftward in its fiscal approach as a result of this transition [1].
The analysts note that, even if Labour adheres to its current fiscal rules, both government spending and taxes are likely to increase under new leadership. There is also the possibility that borrowing could rise if defence spending is excluded from fiscal constraints. The replacement of Chancellor Reeves is considered almost certain once Starmer departs, and any new leader is expected to put their own stamp on fiscal policy, potentially increasing spending and taxes further [1].
Despite these changes, the Labour Party's large parliamentary majority of 165 seats provides a stable platform, and the analysts do not anticipate an early general election before 2028 at the earliest. They emphasize that a new leader is unlikely to call an election soon, especially given Labour's strong position in current polls. While an election in 2026 or 2027 is considered unlikely, the timing will ultimately depend on polling trends under the new Prime Minister [1].
TD Securities concludes that the leadership transition marks the beginning of a gradual end for Starmer, with the Labour Party poised for a leftward policy shift and increased fiscal activity, but with no immediate threat of political instability or early elections [1].
CONCLUSION
The impending Labour leadership race is expected to result in a leftward shift in UK fiscal policy, with higher spending and taxes likely. However, the party's strong parliamentary position means no early general election is anticipated, providing market stability in the near term.
