If the prime minister wants to call an election, he or she has to ask their local distributed queenship node for prorogation and therefore dissolution. Once (year - year_lastelection)== 5, the prorogation subroutine executes automatically.

Things get interesting, though, in the case of event-driven prorogation. The PM, and the Government, serve at the pleasure of their local queenship node and during the confidence of a majority in the lower house of Parliament. In the event they lose one of certain types of parliamentary votes (either an explicit vote of confidence, or one on the budget or on the use of already-committed public funds), this condition is no longer satisfied and signal NOCONFIDENCE is raised.
