Sir Robert Worcester delivered an address to the 28th International Churchill Conference in London in October 2011. Sir Robert is Anglo-American (originally a Kansas City native), and founder of MORI polling in the U.K. You can read a copy of his address here. One quote from his address demonstrates the long constitutional and legal history — the rule of law — which defines the Special Relationship between the United States and Britain. For me, one way of viewing the Special Relationship is that American history did not begin, or a period of British colonial history end, in 1776. Sir Robert mentions some very interesting historical references, which demonstrate the long constitutional and legal history America and Britain share:
Constitutional and Legal: The Rule of Law, the cusp between retributive justice and codified justice, was first expressed in England during the rule of King Æthelbert of Kent, c . 604, recorded in the Textus Roffensus; in the Coronation Oath of Henry I in 1100; and in Magna Carta of 1215, wherein the Rule of Law and Human Rights, if not universal, became, in 1297, the law of the land.
