Parliamentary refers to a system of governance where the executive branch derives its legitimacy from the legislature (parliament) and is accountable to it. In this system, the head of government, often called the Prime Minister, is typically a member of the parliament and is elected by fellow members. This structure promotes collaboration between the legislative and executive branches, allowing for more cohesive policy-making. In a parliamentary democracy, citizens elect representatives to the parliament, which then makes laws and oversees the government. This system is prevalent in many countries, including United Kingdom, Canada, and India, and is known for its ability to adapt to changing political landscapes through coalition-building and party dynamics.
