The "first-past-the-post" electoral system is a voting method in which the candidate who receives the most votes in a constituency wins. This type of plurality voting does not require a candidate to achieve an absolute majority, leading to outcomes where a candidate can win without securing more than 50% of the votes. This system is common in Anglo-American democracies and can result in disproportionate representation, as smaller parties may struggle to gain seats in the legislature despite receiving significant overall support.
