Multiple reports citing the UK Office for Budget Responsibility (OBR) say the government must raise roughly £120 billion per year over the coming years to prevent national debt from rising rapidly. The figures are presented as part of assessments of how to maintain sustainable public finances. The sources state that options to meet this scale of funding include increasing taxes and/or reducing public spending, including spending on welfare. The reporting frames the overall issue as a need to address pressures on debt levels rather than a specific single policy choice. While the articles emphasize the range of possible measures, they agree on the core point: the OBR estimate points to a large adjustment requirement, presented as a combination of revenue-raising and spending restraint. No additional details beyond the cited figure and the broad policy directions are included in the provided excerpts, and the reporting does not specify particular reforms, timelines, or the political stance of any party in a verifiable way beyond the general policy alternatives mentioned.
