How their governments are structured
Sweden is a unitary parliamentary constitutional monarchy; United Kingdom is a unitary parliamentary constitutional monarchy. Both run parliamentary systems, so in each country the head of government depends on a working majority in the lower house — lose confidence and the government falls. The differences are in the detail: thresholds, dissolution powers, and whether a no-confidence motion can succeed without an alternative candidate (constructive no-confidence) or simply on a negative vote. How the executive actually works: in Sweden, prime minister nominated by the Speaker of the Riksdag and confirmed through a negative parliamentarism system where a majority must not vote against the candidate. In United Kingdom, prime minister and cabinet drawn from Parliament under the Crown, with government dependent on House of Commons confidence
