Since the power to call snap elections (the dissolution of parliament) usually lies with the incumbent, they often result in increased majorities for the party already in power provided they have been called at an advantageous time.[3] However, snap elections can also backfire on the incumbent resulting in a decreased majority or in some cases the opposition winning or gaining power. As a result of the latter cases, there have been occasions in which the consequence has been the implementation of fixed-term elections.
