An economics adviser linked to Andy Burnham has called for a major overhaul of the UK tax system, urging government action to streamline how taxes are designed and administered. According to reporting, Lord O’Neill is among several economists who have signed a letter to ministers setting out recommendations aimed at simplifying the tax system. The proposals focus on making the tax framework more straightforward, with the intent of improving efficiency and clarity for taxpayers and businesses. The letter is presented as part of a broader push for reforms rather than a single, isolated change. While specific details of the requested reforms are not fully laid out in the available summaries, all coverage ties the initiative to a coordinated stance by multiple economists and frames it as advice to the government. The outlets agree that the letter seeks to reshape the approach to taxation, emphasizing streamlining and reforming the existing system. Overall, the reporting indicates that the adviser’s comments form part of a collective policy message addressed to the government.
