The optimal way to govern a country, designed from a clean slate.

The United Kingdom's constitution is uncodified, its voting system (First Past the Post) was built for a two-party contest that no longer exists, and its conventions depend on the goodwill of the very people they are meant to restrain. These are not features. They are inherited flaws, defensible only by appeal to age — never by appeal to design.

BIG rejects incrementalism, rejects benchmarking against flawed incumbents, and rejects reverence. It states what government is for, derives the structure that best achieves it, and engineers that structure to survive every adversary and shock we can name.

The objective is explicit and measurable: maximise the long-run wellbeing of citizens — present and future — with rights as an inviolable constraint and informed consent as a precondition.

The central move is to separate two questions every other system conflates: the people decide the ends (values, priorities, acceptable trade-offs); the demonstrably competent decide the means (how best to achieve them), within bounded, reversible authority. Reforming the electoral system comes first — because experts executing a distorted mandate merely deliver the wrong thing competently.
