Andy Burnham unveiled plans on Monday for what he described as the biggest rebalancing of power in the UK, proposing to devolve significant authority away from London to all parts of the country, including English city regions. The former Mayor of the Greater Manchester Combined Authority, now a Member of Parliament for Makerfield, stated that this radical devolution is essential for achieving the higher economic growth the UK needs.

Burnham's policy speech emphasized that "We will never get growth up to the level Britain needs unless every single postcode in the land is set up to contribute to it." His proposal extends beyond England, promising further devolution to Scotland, Wales, and Northern Ireland, though specific details were not provided. He also indicated that Greater London would receive more devolved powers. This initiative aims to empower local regions to drive their own economic development.

Currently, Scotland possesses extensive devolved powers over health, education, justice, and policing, and can set most income tax rates. The Welsh Senedd manages healthcare and education, with some tax-varying powers but no justice or policing authority. Northern Ireland's Assembly, under the Good Friday Agreement, has significant devolved responsibilities in health, education, and housing. English city regions, including Greater Manchester, have seen less extensive devolution, typically covering transport, housing, skills, and health spending.

Despite these existing devolved structures, most economists have not identified a significant overall increase in economic growth rates in Scotland, Wales, and Northern Ireland over the past 25 years. GDP per capita in these nations in 2023 remained broadly similar relative to the UK average as it was in 1998. Analysts caution, however, that this doesn't equate to economic failure, suggesting that devolution may have prevented worse economic outcomes.

Some experts suggest that the impact of devolution on economic growth is complex and difficult to isolate. Factors such as Brexit have also disproportionately affected different parts of the UK, making it challenging to attribute economic performance solely to the extent of devolved powers. The performance of London and the South East of England significantly influences the UK's overall average, potentially masking regional variations.

Burnham's proposal seeks to address this perceived imbalance by giving all regions the tools to foster their unique economic potential. The success of such a broad devolution of power would depend on the specific powers transferred and how effectively they are utilized by regional authorities.

Further details on the scope of powers to be devolved to each nation and city region, and the mechanisms for their implementation, are anticipated. The political and economic implications of such a significant shift in governance will likely be a subject of extensive debate.

Key questions remain about the potential economic benefits, the administrative challenges of implementing widespread devolution, and the long-term impact on national unity and regional prosperity.
