free vote
n.— «Cardinal Cormac Murphy O’Connor, leader of the Roman Church in England and Wales, went public to insist that Labour MP’s should be granted what is known as a “free vote,” the process by which party members are allowed to vote their minds as opposed to being required to succumb to party pressure to vote as an ideological block.» —“Gordon Frankenbrown’s Brave New Labour” by Susan Easton Human Events (Washington, D.C.)
