Ministers Move to Thwart the £72m With Retrospective Residency Rules

The government’s counter-attack on Reform’s war chest took legislative shape: retrospective restrictions on political donors, including tough residency requirements aimed squarely at benefactors who “recently lived abroad”, with a Lords amendment poised to test the £72m’s legality directly. Polling shows a clear majority of Britons back a donations cap; the argument has moved from whether to act to how far back the action reaches.

Residency is the ground the government has chosen because it is the ground where Reform’s donors are weakest: the money’s scale is constitutionally awkward to cap, but its provenance — Hong Kong, Thailand, recent returns timed to the giving — sits naturally inside rules Britain has debated for years about overseas influence, letting ministers frame confiscation as closure of a loophole rather than punishment of a rival. The danger is the precedent’s double edge: retrospective election law survives judicial scrutiny rarely, and a government that loses that case will have gifted Reform both the money and the martyrdom. The public-opinion floor matters here — majority support for caps gives the legislation legitimacy its retroactivity lacks. Watch the drafting of the commencement clause; elections are won and lost in such subclauses.
