Burnham's First Test: 75 Labour MPs Line Up Against Rosebank

Seventy-five Labour MPs have signed a private letter opposing the Rosebank oilfield development, with organisers hoping to reach 100 signatures before it is delivered to Prime Minister Andy Burnham within the next fortnight. The letter, first reported by the Sunday Times, argues that approving Rosebank would destroy the UK's credibility as a global climate leader and would not reduce energy bills.

The rebellion has exposed a split at the top of government. Energy secretary Miatta Fahnbulleh is said to be minded to reject the oilfield, but could be overruled by Burnham. Chancellor John Healy supports the plans. A parliamentary private secretary is reportedly considering resigning if Rosebank goes ahead.

The timing is awkward for the government, which has separately introduced the Energy Independence Bill to ban new North Sea exploration. That legislation would not affect the Rosebank decision. The field was approved in 2022 and is subject to legal challenges. No final decision on drilling has been reported.

The outcome will signal whether Burnham's government prioritises climate credibility or energy pragmatism, and whether backbench discontent can force a U-turn. It also tests the new prime minister's authority: a rebellion of this size, alongside brewing discontent over Europe and welfare, could define his early premiership.

Will the letter reach 100 signatures, and will it be delivered to Burnham as planned? Will Fahnbulleh reject Rosebank, or will she be overruled? Will any ministerial resignations follow if Rosebank is approved? How will the Energy Independence Bill interact with the Rosebank decision, given the bill does not affect it?
