Andy Burnham announced on 29 June 2026 a devolution plan to give metro mayors significantly more power over economic decisions and public services in their regions, under the banner of "good growth in every postcode", according to the BBC. The plan would shift control of investment, skills, transport and housing from central government to local and regional level.

The proposal builds directly on work Burnham has pursued in Greater Manchester since the original Devo Manc settlement in December 2018 — an agreement that gave the region new powers to control spending and policy across multiple areas. It also draws on the Greater Manchester Independent Prosperity Review, which assessed the region's economic strengths and gaps in detail. What Burnham is doing on 29 June is proposing to take the model he's developed over nearly a decade in one city-region and offer it as a template for metro mayors across England.

The most recent concrete example is the £1 billion GM Good Growth Fund, announced in November 2025, which pools investment across more than 30 projects across the city-region. Alongside it sits the Greater Manchester Baccalaureate (the MBacc), a new technical education qualification. The government confirmed its backing for this programme in December 2025, with full implementation planned for 2026. Both the Fund and the MBacc sit within the "good growth" framework Burnham is now proposing as a model for use elsewhere.

The argument itself is straightforward: decisions about skills training, investment, transport, housing and linked public services produce better results when made by people and institutions closer to the communities affected. This reasoning has long underpinned the case for devolved governments in Scotland (Holyrood), Wales (the Senedd) and Northern Ireland (Stormont). Applying the same logic systematically to English metro mayors, however, raises unresolved questions about how institutions should work and how money should be allocated. English devolution is not a single agreed settlement; it is a collection of different deals, each negotiated separately between individual mayors and the Treasury and Ministry for Housing, Communities and Local Government, with no common rules across regions.

Burnham's plan appears designed to push against this fragmentation. The phrase "good growth in every postcode" suggests he is framing devolution around spatial fairness — not just whether a region grows economically, but whether that growth reaches across the whole area. Whether this can be achieved with current funding levels, or whether it would require a rethink of how central government money is distributed to regions (the Barnett formula and its successors) and greater freedom for regions to raise their own taxes, is the central question Whitehall officials will examine.

The timing carries political weight. Burnham continues as Greater Manchester Mayor, and his influence in Labour's thinking on economic strategy has grown since the 2024 general election. Any major policy blueprint published under his name inevitably carries a positioning dimension alongside its policy content. That said, any significant speech from any metro mayor does the same. The technical detail of the plan itself is what officials and combined authority leaders across England will assess in the coming weeks.

For those working in devolved and mayoral government, the operational specifics will be decisive. The MBacc's 2026 launch date offers a concrete milestone to judge the wider "good growth" model against. The pipeline of 30-plus Greater Manchester projects provides another. How other mayoral authorities — the West Midlands, West Yorkshire, London — respond will determine whether Burnham's blueprint remains a Manchester proposition or becomes a genuine national framework.
