At the Oxford Union, debates are carried out in teams. My team consisted (from left to right) of a Liberal Democrat Member of Parliament from Cambridge, Julian Huppert, myself, David Browne, the student member from Merton College, and Richard Cowan, the former Director of the National Organization for the Reform of Marijuana Laws (NORML). We were opposed by Joseph Miles from Wadham College, Kathy Gyngell fo the Centre for Policy Studies, Neil McKeganey, the Director of the Centre for Drugs Misuse Research, and Sarah Graham who is on the U.K. Advisory Council of the Misuse of Drugs. The Oxford Union is one of the oldest and most prestigious debating societies and is strongly committed to the principle of free speech. Past debate presenters include the Dali Lama, Mother Teresa, Albert Einstein, former US Presidents, UK Prime Ministers, and other leading politicians and diplomats, as well as leaders from the field of art and entertainment.
