When the debate concludes, or when the closure is invoked, the motion is put to a vote. The house first votes by voice vote; the Speaker or Deputy Speaker puts the question, and Members respond either "Aye!" (in favour of the motion) or "No!" (against the motion). The presiding officer then announces the result of the voice vote, but if his or her assessment is challenged by any member or the voice vote is unclear, a recorded vote known as a division follows. The presiding officer, if she or he believes that the result of the voice vote is clear, may reject the challenge. When a division occurs, members enter one of two lobbies (the "Aye" lobby or the "No" lobby) on either side of the chamber, where their names are recorded by clerks. A member who wishes to pointedly abstain from a vote may do so by entering both lobbies, casting one vote for and one against. At each lobby are two tellers (themselves members of the house) who count the votes of the members.
