What is the method of delay by making lengthy speeches?

The method of delay by making lengthy speeches, often referred to as "filibustering," involves prolonging debate on a legislative issue to prevent a vote or to push for a specific outcome. This tactic allows one or more individuals to speak for an extended period, thus consuming time and potentially hindering the progress of other business in a legislative body. It is commonly used in parliamentary systems and can be an effective strategy for minority groups to voice their concerns or negotiate terms.
