Britain’s expected next prime minister is not yet in office, but the battles that may define his government have already begun.
Andy Burnham, widely seen as Labour’s likely next leader and on course to enter Downing Street later this month under the party’s timetable, is being drawn into a trio of disputes that cut to the center of Britain’s economic and political future: whether to permit more North Sea oil and gas development, whether to push for greater public control of utilities, and whether to accept a defence spending increase that allies say was announced without a credible plan to pay for it.
Taken together, the clashes amount to an early test of what a Burnham premiership would mean in practice. They pit climate goals against energy security, public ownership against investor confidence, and military ambition against the fiscal constraints that have hemmed in successive British governments.
A decision on the North Sea
One of the first choices facing Mr. Burnham could be over projects such as Rosebank and Jackdaw, long-running symbols of Britain’s unresolved argument over fossil fuels in an era of climate targets and geopolitical instability.
Supporters of further North Sea development say Britain remains vulnerable to energy shocks and should not hasten the decline of domestic production while households and industry are still exposed to volatile global markets. They argue that new drilling helps preserve jobs, tax revenue and a measure of strategic resilience, particularly after the energy crisis that followed Russia’s invasion of Ukraine reshaped thinking across Europe about supply security.
Critics, including many inside Labour, counter that new projects would do little to shield consumers from high prices, which are largely set on international markets, while locking in emissions inconsistent with Britain’s legally binding climate commitments. Rosebank in particular has become a political shorthand for that argument: a vast field promising jobs and output, but also years of future carbon pollution.
For Mr. Burnham, the question is more than technical. It would send an early ideological signal about whether his government intends to tilt decisively toward renewables and managed transition, or to adopt a more permissive stance toward oil and gas in the name of security and industrial pragmatism.
That choice matters because Labour has not fully resolved the tension within its own coalition. Trade union voices and some regional leaders have emphasized the employment consequences of a rapid shift away from the North Sea. Environmental advocates and many younger party activists have pressed for a cleaner break.
Utilities and the market
At the same time, Mr. Burnham’s preference for greater public control over essential services is colliding with the financial realities of Britain’s privatised utility system, nowhere more sharply than at Thames Water.
The company’s crisis has become a national proxy for a larger argument about whether the model built in the 1980s and 1990s can still command political consent. Years of public anger over sewage discharges, debt-loaded balance sheets, executive pay and underinvestment have fueled calls for tougher state intervention. Burnham allies have spoken in broad terms about reversing parts of the privatised settlement in water and energy, with Thames Water viewed as the most likely first test case.
But any move toward public ownership, or even a more muscular form of state control, would reverberate well beyond one company. Creditors linked to major U.S. investors have been trying to assemble a rescue package for Thames Water, and a British government perceived as hostile to investor rights could unsettle infrastructure markets at a moment when the country still depends on private capital to finance everything from power networks to transport and housing.
That is why the issue is being watched closely in New York as well as Westminster. If Burnham opts for special administration or another route that leaves creditors taking sharper losses, supporters may hail it as the overdue reassertion of democratic control over a failing monopoly. Opponents would almost certainly present it as a warning that Britain has become a harder place for global investors to commit long-term money.
The ambiguity in Burnham’s own language has only heightened the scrutiny. “Public control” can mean several things: stricter regulation, capped returns, new public stakes, not-for-profit structures or outright nationalisation. The cost and consequences differ enormously.
A defence plan and a funding hole
The sharpest immediate row, however, is over defence.
On June 30, Prime Minister Keir Starmer announced a Defence Investment Plan that ministers said would total about £298 billion over four years, including a £15 billion uplift intended to raise military spending to roughly 2.7 percent of gross domestic product by 2029. The pledge was meant to project seriousness at a time when European governments are under intense pressure to spend more on security.
Instead, it has also opened a bitter argument over how the money will be found.
According to figures circulating in Westminster, part of the increase is to be paid for through cuts or delays to road and energy projects, while roughly £5 billion remains unfunded and would need to be addressed in a future budget. That has provoked anger not only from opposition politicians but from Labour figures whose constituencies now face lost or postponed infrastructure spending.
Hamish Falconer, a Labour minister, was among those affected by transport cuts linked to the plan, while Robert Jenrick, now a Reform MP for Newark, also criticized the loss of local road improvements. The backlash has underscored how quickly a national security announcement can turn into a highly local political problem.
Inside Labour, the complaint runs deeper than the roads themselves. Allies of Mr. Burnham have been described as furious that such a large funding challenge could be handed to an incoming leadership after Labour spent years accusing Conservatives of making promises without fully financing them. For a party that sought office on a message of discipline and credibility, the charge is politically toxic.
The fiscal shape of what comes next
That is the thread connecting all three disputes: they are arguments not just about policy, but about the limits of the British state.
A government that wants cleaner energy must decide how fast it can move without destabilizing jobs and supply. A government that wants more public control of utilities must decide how much risk it is willing to pose to investors and to the public finances. A government that wants stronger armed forces must decide what voters will give up, or pay more for, to fund them.
Mr. Burnham has built his recent politics around devolution, reindustrialisation and the promise that essential systems should work more clearly in the public interest. That agenda has broad appeal after years of stagnant living standards and visible failures in infrastructure and public services. But it also points toward more state direction at precisely the moment when borrowing costs remain elevated and economic growth is weak.
The defence row makes that tension especially stark. Military spending has become harder for mainstream politicians to resist as Russia’s war in Ukraine grinds on and as doubts linger about the durability of American security guarantees in Europe. Yet every additional pound for defence must come from taxes, borrowing or cuts elsewhere. In Britain, that arithmetic has a way of intruding quickly.
A leadership tested before it begins
None of the decisions is final. Mr. Burnham is still the expected, not formal, successor. It is unclear whether he would ultimately approve Rosebank or Jackdaw, whether his utility plans would amount to regulation or ownership, or whether Thames Water will be rescued by creditors rather than pulled into a more overtly state-led solution. The final shape of the defence budget gap is also unresolved.
But the outline of the challenge is already visible. Before he has had the chance to set out a full program in office, Mr. Burnham is being forced to confront the central trade-offs of governing Britain in 2026.
The choices he makes in the coming weeks may tell voters and markets alike whether the next phase of Labour rule will be defined by continuity wrapped in new language, or by a more confrontational attempt to remake the state’s relationship with industry, infrastructure and capital.
