This market resolves to 'YES' if, before January 1, 2028, the UK government legally enacts a new law mandating compulsory military service for its citizens. The legislation must require any UK citizen or subgroup thereof (e.g. restricted by age, gender or profession) to serve in the UK Armed Forces. This includes any form of mandatory enlistment, regardless of duration or capacity (combat or non-combat roles).

It does not count if the legislation is only proposed or discussed without formal enactment. Non-military national service, or voluntary enlistment incentives do not qualify.

The outcome is determined by the passage of a law, not its implementation or enforcement.
