Andy Burnham is poised to enter Downing Street with sweeping plans to shift power out of Westminster and into England's regions, despite never having faced voters as a would‑be prime minister at a general election. Before he can begin his promised overhaul of how Britain is run, one challenge threatens to overshadow his first days in office: who gave him the mandate to do it?
Burnham is expected to become Britain's next prime minister following Sir Keir Starmer's departure, inheriting Labour's parliamentary majority and using it to drive a far more radical devolution agenda than the party set out at the last election. That transition may be constitutionally valid, but critics argue legality is not the same as legitimacy, particularly for a leader promising far‑reaching procedural change.
