Definition: Closure, also known as cloture, is a procedure used in a legislative body to end debate and call for an immediate vote.

Example: In the United States Senate, if a bill is being debated and a senator wants to end the discussion and move to a vote, they can call for closure. This means that the debate will end and a vote will be taken.

Explanation: Closure is used to prevent endless debate and ensure that a decision is made. It allows for a vote to be taken and a conclusion to be reached. The example illustrates how closure is used in the United States Senate to move the legislative process forward.
