Overview
- Mr Burnham said on Sunday he was told by UK officials that Russia interfered in the 2016 Brexit referendum, the first time a serving prime minister has publicly made that claim.
- He has formally reopened Britain’s relationship with the EU and left open the possibility of a manifesto pledge to seek re-entry while the government insists it will not rejoin the single market or customs union in this parliament.
- Polling commissioned by the European Movement with Observant shows majority public support for talks on rejoining and strong backing among Labour voters, and the European Movement has sent No.10 a roadmap aiming for accession by about 2036.
- Brexiteer figures, former Vote Leave organisers, Conservative MPs and Reform UK have mobilised cross-party resistance, and a six-figure public petition is due for debate in Westminster Hall.
- Practical barriers remain significant—EU accession needs member-state agreement and likely a referendum or clear electoral mandate—so the issue will be shaped by upcoming parliamentary debates, a UK–EU summit and the election timetable.
