Multiple reports say the Prime Minister is expected to unveil plans on Friday to deepen devolution in England by allowing mayors to receive a share of income tax revenue to spend locally. The proposals are described as part of a broader devolution push associated with Andy Burnham. According to the reports, the arrangement would shift control of a portion of income tax receipts to local mayors, who would then use the funds for local priorities. One report also says the plans involve the possibility of using the local tax income to deliver tax rebates to residents, framing the policy as a direct financial benefit linked to the distribution of the revenue. The reporting also indicates political interest across mayoral alignments, including Conservatives and Reform mayors, who are said to be involved in plans to adopt or support the approach. The sources agree on the central element: a new mechanism for mayors to gain access to part of income tax receipts, alongside the expectation that the Prime Minister will announce the details on Friday. However, the specific design of the revenue share and how any rebates would be implemented are not detailed in the provided excerpts.
