Miatta Fahnbulleh has been appointed secretary of state for energy security and net zero in the new Andy Burnham government.

She replaces Ed Miliband, who has become foreign secretary.

Ms Fahnbulleh, the MP for Peckham since 2024, was previously a junior housing minister (September 2025-May 2026) and a junior minister at the department of energy security and net zero (July 2024-September 2025).

In 2024, the Guardian said of her:

“Fahnbulleh has pushed hard for serious action on the climate crisis and has advocated more urgency in the UK’s response. She is likely to be the big brain of the party’s soft left.”

She told LabourList in 2025 the route to long-term savings in energy was “weaning ourselves off fossil fuels and wholesale on the global market, which is why we are moving to deliver clean home-grown energy at such pace”.

She said:

“When we started, people were quite sceptical if we could get to clean energy by 2030. I think everyone has been staggered at the pace that we are driving through the things we need to do; removing the ban on onshore wind, the biggest ever auction that’s been delivered for renewables.

“We are absolutely driving it – and in the end, that is the way in which we will get bills down.”

Before becoming an MP, Ms Fahnbulleh was chief executive of the New Economics Foundation (2017-2023). She also worked as the director of policy and research at the Institute for Public Policy Research and was head of cities in the policy unit at the Cabinet Office (2011-2013).

She studied philosophy, politics and economics at University of Oxford and has a PhD in economic development from the London School of Economics.

She was born in Liberia and was brought to the UK in 1986 as a five-year-old by her parents fleeing the country’s civil war.

Reaction

Friends of the Earth energy lead, Imogen Dow, said:

“As someone who’s been vocal about the need to reduce our reliance on fossil fuels and did a lot to shape the government’s Warm Homes Plan under Ed Miliband, it’s encouraging that Miatta Fahnbulleh has been appointed as his successor.

“She will, of course, inherit the same challenges. She must hold the line against harmful fossil fuel expansion – including the highly contentious Jackdaw and Rosebank fields – make cheap, clean energy available to all and build on Ed Miliband’s efforts to scale up our renewable power capacity.

“Today’s announcement to cut VAT from energy bills is certainly a step in the right direction, but this should come alongside a new social tariff to help those on the lowest incomes, which will make a meaningful difference in the long-term. Insulating more homes and boosting Britain’s homegrown wind and solar power production are how we can also drive down bills and slash climate-warming emissions for good.”
