Parliamentary filibuster refers to a delay method of prolonging debates in parliament. It is a parliamentary procedure where a member of parliament speaks for a long time in order to delay or prevent the passing of a bill or motion.

Filibusters can be used as a tool by the minority party in parliament to prevent the majority party from passing legislation that they disagree with.
