A politicalparty platform (North American English),party program, orparty manifesto (preferential term in British and often Commonwealth English) is a formal set of principal goals which are supported by apolitical party or individualcandidate, to appeal to the general public, for the ultimate purpose of garnering the general public's support and votes about complicated topics or issues. A component of a political platform is often called aplank – the opinions and viewpoints about an individual topic, as held by a party, person, or organization. The word "plank" depicts a component of an overall political platform, as a metaphorical reference to a basicstage made of boards orplanks of wood. The metaphor can return to its literal origin whenpublic speaking ordebates are actually held upon a physical platform.[original research?]
In the United Kingdom and certain other countries, the party platform is referred to as the party's "manifesto"[1][2] or political programme. The manifesto contains election pledges, or election promises. Across theWestern world, political parties in power are highly likely to fulfill their election promises, research has found.[3]
The first known use of the wordplatform was in 1535. The wordplatform comes fromMiddle Frenchplate-forme, literally meaning "flat form".[4] The political meaning of the word to reflect "statement of party politics" is from 1803, probably originally an image of a literal platform on which politicians gather, stand, and make their appeals.[5]

A 2017 study in theAmerican Journal of Political Science that analyzed 12 countries (Austria, Bulgaria, Canada, Germany, Ireland, Italy, the Netherlands, Portugal, Spain, Sweden, United Kingdom, and United States) found that political parties in government fulfill theirelection promises to voters to a considerable extent.[3] The study determined that:
Parties that hold executive office after elections generally fulfill substantial percentages, sometimes very high percentages, of their election pledges, whereas parties that do not hold executive office generally find that lower percentages of their pledges are fulfilled. The fulfillment of pledges by governing executive parties varies across governments in ways that reflect power-sharing arrangements. The main power-sharing arrangement that impacts pledge fulfillment distinguishes between single-party governments and coalitions, not between governments with and without legislative majorities. We found the highest percentages of pledge fulfillment for governing parties in the United Kingdom, Sweden, Portugal, Spain, and Canada, most of which governed in single-party executives. We found lower percentages for governing parties in Germany, the Netherlands, Austria, Bulgaria, Ireland, and Italy, most of which governed in coalitions. Pledge fulfillment by U.S. presidential parties lies at the higher end of coalition governments, which suggests that U.S. presidents are more constrained than governing parties in single-party parliamentary systems, but less constrained than most governing parties in multiparty coalitions.
Other research on the United States suggests thatDemocratic Party andRepublican Partycongresspeople voted in line with their respective party platforms 74 per cent and 89 per cent of the time, respectively.[6]
