Whitehall's Economic Choreography: Burnham's Bid to Unseat the Treasury Brain

Andy Burnham’s latest move to reconfigure Britain’s economic policymaking is not merely a bureaucratic reshuffle; it is a direct challenge to the Treasury's entrenched power, a struggle that has historically defined Prime Ministerial tenures. Burnham, far from the first to confront this leviathan, is attempting to dismantle what many perceive as a ‘Treasury brain’ that prioritizes fiscal control over dynamic growth.

This week, the Prime Minister detailed his plan to transfer control of growth policy from the Treasury to a new No 10 department, strategically located in Manchester. This initiative echoes Harold Wilson’s short-lived Department for Economic Affairs (DEA), an earlier attempt to inject long-term vision into British economic strategy. The DEA's founding principle, “We must pay our way in the world and produce more wealth inside this country,” resonates with Burnham's stated ambition to unblock systemic impediments.

The core of Burnham's critique, as articulated to the Times, is that the Treasury’s “dual job of growth and control of the public finances sometimes clouds the growth mission.” He argues that a No 10-led growth mission would possess “maximum power to unlock the blockages where they exist in the Whitehall system.” This sentiment reflects long-standing grievances, particularly from the left, who accuse the Treasury of institutional caution and short-term thinking. Examples cited include the slashing of winter fuel allowance and concessions on a bank windfall tax, decisions attributed to this 'Treasury brain'.

Burnham's new prime minister’s department, to be overseen by cabinet ally Louise Haigh, is intended to foster fresh thinking. He asserts that the “new No 10 North innovation is more significant than people realise.” This sentiment aligns with one of the few detailed policy publications from the new cabinet, which focused on radical devolution plans. The PM’s hope is that empowering metro mayors will consolidate growth policies currently fragmented across Whitehall.

Ruth Curtice, director of the Resolution Foundation thinktank and a former Treasury official, views this coordination as the most effective application for the Manchester-based unit. She notes that “No one department has all of the levers – the Treasury don’t own all of the levers,” suggesting that greater force behind this priority from No 10 is a positive development. Michael Jacobs, emeritus professor of political economy at the University of Sheffield and a former Brown adviser, draws parallels to the Office of Climate Change, which successfully coordinated cross-governmental policy. This structural re-engineering signifies a deep-seated desire to move beyond the historical power struggles that saw figures like Boris Johnson all but force Sajid Javid’s resignation, or Margaret Thatcher favour Alan Walters over Nigel Lawson, leading to Lawson's furious departure. Burnham is not just shifting offices; he is attempting to fundamentally rewire the mechanism of national economic ambition.
