Daniel Bethlehem is a barrister and arbitrator practising in the field of public international law from Twenty Essex chambers in London.  From May 2006 to May 2011, he was the principal Legal Adviser of the U.K. Foreign & Commonwealth Office, now the Foreign, Commonwealth and Development Office (FCDO).  Prior to this, he was in practice at the Bar and, in parallel, Director of the Lauterpacht Centre of International Law at the University of Cambridge and Fellow of Clare Hall, Cambridge.  In addition to his legal practice, Daniel is the director of Legal Policy International Ltd, a strategic consultancy advising on high legal content international policy and political issues.  He was knighted in June 2010.

In parallel with his legal and advisory practice, Daniel is Visiting Professor in the Department of War Studies at King’s College London.  His previous academic appointments include the London School of Economics and Cambridge University, at which he taught graduate courses in United Nations law, GATT/WTO and international trade law, and advanced general courses in public international law, including the use of force, the law of armed conflict / international humanitarian law, the law on State responsibility, immunities, and more.  He has also been a Visiting Professor in the Department of Law at Columbia University in New York and a Senior Fellow at the Human Rights Institute of Columbia Law School

Amongst other appointments and affiliations, Daniel is Chair of the Advisory Board of the Lauterpacht Centre of International Law at the University of Cambridge, and a Member of the Advisory Committee on International Law of the U.S. Department of State.
