When King John signed the Magna Carta in 1215, limiting sovereign power, he did not consider the legitimacy of the power of financial institutions or global corporations. 800 years later, Baroness Helena Kennedy invites us to draw on the blueprint of Magna Carta in a twenty-first century context, highlighting the excesses of power that warrant curtailment today. Kennedy turns to contemporary abusers of arbitrary power, asking how we can ensure the accountability of our financial institutions. Do global giants such as Google and Amazon operate outside of the law? In a pensive revival of the 4,000 word cornerstone of British politics, Kennedy sparks timely debates concerning the place of freedom, human rights and democracy in our world, in which an unwritten constitution can often muddy the waters of transparency.
