Speaker is the name of the person in charge of some legislatures, usually the lower house.
House of Commons of the United Kingdom [change]
The Speaker is elected by other members, usually he or she is a member of the government party, but leaves his or her party because the Speaker must be neutral (not like one side more than another). The Speaker does not vote. If the Speaker wants to stand in for re-election the other parties do not oppose him to show he is neutral.
