A "flip-flop" (used mostly in the United States), U-turn (used in the United Kingdom, Ireland, Pakistan, Malaysia, etc.), or backflip (used in Australia and New Zealand) is a derogatory term for a sudden real or apparent change of policy or opinion by a public official, sometimes while trying to claim that the two positions are consistent with each other. It carries connotations of pandering and hypocrisy. Often, flip-flops occur during the period prior to or following an election in order to maximize the candidate's popularity.
