The UK uses the shared political and economic simulation with a parliamentary monarchy, country-specific electorate data, Commons elections, devolved regional offices, Prime Minister formation votes, and an era-aware Cabinet.

Regions and Commons seats#

UK gameplay uses 12 regions for residency, elections, demographics, and regional policy. The live modern Commons allocation comes from UK_COMMONS_SEATS in :

Code Region Commons seats
LON London 75
SEE South East England 90
SWE South West England 58
EAE East of England 60
EMI East Midlands 47
WMI West Midlands 57
YHU Yorkshire and the Humber 54
NWE North West England 75
NEE North East England 27
SCO Scotland 57
WAL Wales 32
NIR Northern Ireland 18

The modern total is 650, with a majority threshold of 326. The 1953-default preset uses UK_COMMONS_SEATS_1953, totaling 625 seats with a 313-seat majority. Do not use the UK_REGIONS.constituencies display metadata for seat allocation.

UK regions use adapted census dimensions and country-specific group weights. They do not simply reuse the US demographic group ids.

House of Commons elections#

See UK Elections for preset-aware seat maps, vacancy handling, and cycle timing.

Government formation#

The canonical record is governmentFormations, updated through . Its status is pending, formed, or collapsed.

After a Commons cycle, seat totals are refreshed and lower-chamber members may nominate a Prime Minister through the shared appointment-vote flow. Formation may be recorded as a majority, coalition, or minority government. Coalition party ids and their supporting seats are included when applicable. A successful appointment writes the PM to governmentFormations, marks the government formed, and clears the previous cabinet.

Votes of no confidence use a whole-chamber simple majority. Any eligible lower-chamber member may propose and vote; the mechanism is not restricted to the governing block. See Parliamentary Government and PM and No Confidence.

The canonical Downing Street route is /country/uk/executive. /executive/uk and /uk/government redirect there.

Cabinet#

The sitting PM appoints eligible player-controlled MPs to era-aware positions from UK_CABINET_POSITIONS. Appointees need not belong to the governing party or coalition. An appointment starts a 24-turn lock for that cabinet seat; the lock remains if the minister is fired. See UK Cabinet.

Legislation#

UK national bills use UK_NATIONAL_CONFIG in :

  1. The Commons votes by simple majority.
  2. About 28% of passed bills enter a 1 to 2 turn Lords-revision hold.
  3. The bill then receives automatic Royal Assent and is enacted.

The Lords are not a playable elected chamber. While governmentFormations.status is pending, the UK lifecycle is frozen through skipWhenGovPending and resumes automatically when a government forms.

Devolved regional executives#

Scotland, Wales, and Northern Ireland use First Minister labels; London uses a Mayor. English regions outside London do not have a devolved executive office. Regional legislation and assent use the country-aware regional office mapping described in State-Level Power.
