UK Prime Minister Andy Burnham sets out a devolution-led growth plan and unwavering support for Ukraine in his first parliamentary statement
Burnham, who replaced Starmer in July, addressed the House of Commons on 1 September and faced his first question session on 2 September. He pledged a tax cut on energy bills, stronger public oversight of public services and full funding of the defence investment plan.
Andy Burnham, who became prime minister in place of Keir Starmer on 20 July 2026, set out a theory of growth based on devolution to the regions in a statement to the House of Commons on 1 September. The statement included a 'Number 10 North' unit to coordinate central decisions and stronger public control over water, the energy grid and transport. He said support for Ukraine would not change in the face of any threat. He also announced that the number of irregular migrants arriving in Dover over the summer months had halved compared with the previous year. At his first question session on 2 September he pledged to fully fund the Defence Investment Plan, cut taxes on electricity bills and present a 10-year economic roadmap by the end of the year.
The government's agenda coincides with gilt yields at their highest since 1998. Conservative leader Kemi Badenoch asked how these pledges would be funded in the face of rising borrowing. For markets, the real question is how promises of public control and expanded spending will be reconciled with the fiscal rules. The rise of the 10-year yield above 5% during July's leadership change had shown investors' sensitivity to fiscal credibility. The emphasis on continuity in defence signals that the UK's role in NATO and the European security architecture will be preserved.
Talay assessment
Bottom line
Burnham's agenda is politically ambitious, but the real constraint is the gilt market rather than parliament: an energy tax cut, public control and full funding of the defence plan are being promised at once while yields are at their highest since 1998. The 10-year yield exceeding 5% during July's leadership change showed the market's sensitivity to fiscal credibility. The most likely path is for the pledges to be phased in line with the fiscal rules.
Likely effects
- UK borrowing costsNegative1–6 months
Spending pledges without clear funding could add a further risk premium to already high gilt yields, raising the Treasury's interest bill and borrowing costs for households and companies.
- European securityPositive1–6 months
The commitment to continuity in support for Ukraine and in the Defence Investment Plan signals that, despite the change of leader, the UK's role in NATO and the European security architecture will be preserved.
Possibilities, ranked
- 1Phased delivery within fiscal rules55%
Pledges are spread over time and some are scaled back; the year-end roadmap stresses adherence to the fiscal rules and the gilt market calms.
Watch: The funding framework in the 10-year economic roadmap due by the end of the year
- 2Retreat under market pressure35%
Funding uncertainty pushes gilt yields up again; the government is forced to retreat on the energy tax cut or public control plans.
Watch: The 10-year gilt yield rising back above 5%
- 3Expansion without market reaction10%
The government implements its spending expansion without a marked market reaction and yields decline.
Watch: Gilt yields falling after budget announcements
