Based on the search results, Andy Burnham became Prime Minister of the United Kingdom on July 20, 2026 — one day before Kemi Badenoch's tweet. The claim that "Burnham has new policies" is straightforwardly and abundantly supported by multiple primary and reputable news sources. **Evidence:** 1. **GOV.UK official speech (July 20, 2026):** Burnham's first speech as Prime Minister, published on the UK government website, outlined numerous new policies, including ending rough sleeping, building more council homes, a "new economic model," re-industrialising Britain using public procurement, changing the education system, and more mental health support. He also announced a forthcoming "10-year plan for Britain." 2. **The Guardian (July 21, 2026):** Reported that Burnham announced removing VAT from electricity bills from October 1 (costing £850m), reducing the national bus fare cap from £3 to £2, accelerating a national care service, and major Whitehall restructuring including a new Office for the Prime Minister and Cabinet. 3. **BBC News:** Published a detailed article listing Burnham's policies across devolution, housing (largest council house building programme "since the post-War period"), social care reform, rough sleeping, water/energy public control, welfare reform, personal taxes, business rates reform, and electoral reform. 4. **Bloomberg (July 20, 2026):** Reported on Burnham promising a "new economic model" in his first speech as PM. The evidence overwhelmingly confirms that Burnham has announced and advocated for a wide range of new policies as of July 21, 2026. The claim is factual and well-documented across government sources and multiple independent news organizations.
