 Williams has supported the Robin Hood tax campaign since March 2010, re-affirming his support in a November 2011 article he published in the "Financial Times".He is also a vocal opponent of tax avoidance and a proponent of corporate social responsibility, arguing that "economic growth and prosperity are about serving the human good, not about serving private ends".The response of Williams to a controversy about the teaching of creationism in privately sponsored academies was that it should not be taught in schools as an alternative to evolution.
