In parliamentary politics, balance of power is a situation in which one or more members of a parliamentary or similar chamber can by their uncommitted vote enable a party to attain and remain in minority government. The term may also be applied to the members who hold that position. The members holding the balance of power may guarantee their support for a government by either joining it in a coalition government or by an assurance that they will vote against any motion of no confidence in the government or will abstain in such a vote. In return for such a commitment, such members may demand legislative or policy commitments from the party they are to support. A person or party may also hold a balance of power in a chamber without any commitment to government, in which case both the government and opposition groupings may on occasion need to negotiate for that person's or party's support.
