Free vote

For thoughtful child sponsors
A free vote is a vote within a Westminster System parliament's House of Commons in which a party does not take a position and members are allowed to vote according to their own beliefs. This is most likely to occur in cases where there is a moral issue such as the death penalty. In many such cases, pressure is brought to bear on the government party to permit a free vote.
