Repeal the Fixed Term Parliament Act: Pending
The Fixed Term Parliament Act introduced fixed-term elections to the Westminster parliament for the first time. Under the provisions of the Act, parliamentary general elections must be held every five years. However, a vote of no confidence in the government, or a two-thirds majority vote in the House of Commons, can still trigger a general election at any time. This happened in 2017 when Theresa May called a snap election on this basis.

The Fixed Term Parliament Act remains in force.
