The significance of a political manifesto during elections lies in its role as a formal document outlining a party's policies, values, and goals for governance. It serves as a key communication tool to inform voters about what to expect if the party is elected. A well-articulated manifesto can help parties articulate their vision, garner support, and differentiate themselves from opponents. Additionally, it creates a basis for accountability, as voters can review the outcomes of policies implemented post-election against the promises made in the manifesto.
