Prime Minister Andy Burnham is facing a growing backbench revolt over the Rosebank North Sea oilfield, with up to 100 Labour MPs potentially opposing the project. Seventy-five MPs have already signed a private letter on the issue, which is expected to reach Downing Street within two weeks.
The campaign is being led in part by Labour's 2024 intake of MPs, many of whom were elected on platforms that placed climate policy and energy transition at the centre of their agenda. The scale of the potential rebellion suggests that the disagreement is no longer confined to a small group of vocal critics on the party's left flank but reaches into the wider parliamentary party.
It remains unclear whether Burnham will change his position on Rosebank. The government has not yet signalled a shift, and the pressure from backbenchers is building at a time when the leadership is also contending with discontent on other fronts. Frustration has been growing over Labour's European policy and over changes to the welfare system, and there are indications that rebellions on Europe and welfare could also build this week.
The combination of multiple sources of dissent raises the stakes for the leadership. A sustained revolt across several policy areas could test the authority of the new prime minister and the discipline of his parliamentary majority. Whether the Rosebank letter prompts a change in government thinking, or hardens opposition within the party, will become clearer once the letter is delivered and the government sets out its response.
