It is with immense sadness that the PNBA announces the death of Mark Cannon QC on 22 January 2022. Mark was the Chair of this Association from December 2009 to December 2011 and before that Vice-Chair to the now Lady Justice Carr. He was an energetic and committed supporter of the Association’s work and of the development of the professional negligence Bar.He also made a major contribution to legal writing about professional liability. He was an editor of Jackson & Powell on Professional Liability from 1992 until his death, and was one of the three general editors of the latest (9th) edition. He was co-author of Cannon & McGurk, Professional Indemnity Insurance (1st ed. 2010, 2nd ed.2016), which is the leading text in its field for practitioners. He was also a Bencher of the Middle Temple. Mark combined a fierce and vast intellect with a friendly charm, and we are sure he will be much missed by all of his many friends and colleagues both at 4 New Square where he was Head of Chambers until late last year and at the wider Bar. We will circulate any further information as soon as it is released.
