労働運動
The term has been used by left-wing commentators to criticise centrist views. Some traditional left-wingers regard the first Labour Prime Minister Ramsay MacDonald as a "champagne socialist" who betrayed the Labour movement. MacDonald's lavish lifestyle and his mingling with high society is supposed to have been a corrupting influence that led to the end of the Labour Government in 1931 and the eventual formation of the National Government. More recently, the epithet has been levelled at supporters of the New Labour movement which brought Tony Blair to power in 1997.
