Budget must begin to deliver prime minister's pledges, says Chris Mason

John Healey's first Budget will be judged on whether it starts to fulfil the prime minister's promises, with measures to ease the cost of living—particularly on energy—and announcements on devolution expected to be front and centre, writes Chris Mason.

The Budget to be presented by John Healey will be closely watched for early signs that the government is starting to deliver on the prime minister's commitments, the BBC's Chris Mason writes. At the heart of that test, Mason argues, will be measures aimed at relieving pressure on households and a clear stance on the distribution of powers and funding across the United Kingdom.

Cost-of-living support, and energy bills in particular, are likely to dominate public and political attention. With many households still struggling with household bills, any announcements that seek to limit or mitigate rising energy costs will be read as a direct response to voters' immediate concerns and a measure of the government's priorities.

Devolution is expected to be another key element of the Budget. Mason notes that declarations on the allocation of resources and the scope of devolved powers will be important not only for the administrations in Scotland, Wales and Northern Ireland, but also for the government's broader efforts to show it can make and implement policy promises at a national level.

Taken together, the package Healey sets out will be interpreted as an early indication of how the government plans to balance short-term relief for households with longer-term fiscal strategy. Mason suggests that the Budget will therefore be a crucial political moment, signalling whether ministers can translate pledges into tangible policies that affect people's everyday lives.
