Head of chambers

Mr Mark Cannon QC

4 New Square is a leading commercial and civil set of barristers comprising 84 members, of whom 31 are Queen’s Counsel. Its members are recognised as leading practitioners in a wide range of fields including commercial law, professional liability, international arbitration, insurance and reinsurance, commercial chancery, construction and engineering, public law, financial services, costs and sports law.

In recent years individual members of 4 New Square have consistently been included as leading practitioners in the two main legal directories (Legal 500 and Chambers & Partners) and 4 New Square has been named as the top set for professional negligence at the Chambers UK Bar Awards in 2015, 2016 and 2019. Jackson & Powell on Professional Liability (the main text in this area) is written and edited by current and former members of chambers.

Chambers attracts a large amount of junior advocacy work which reflects the emphasis on developing pupils and junior tenants into experienced advocates to equip them for a successful career at the Bar.

4 New Square is a member of the Pupillage Gateway. For information regarding applications and deadlines, please visit the Pupillage Gateway website.

We strongly encourage students to apply for a mini-pupillage with us as we believe that they allow prospective applicants to get a real understanding of the work done in chambers. Mini-pupils also have the opportunity to meet members of chambers and get a feel for the working environment.

Mini-pupillages last for two days and, save in exceptional circumstances, take place in specific weeks in June, July, November and December of each year. Mini-pupillages do not involve formal assessment but we do record feedback on your likely suitability for pupillage in chambers. Mini-pupillage application details can be found on our website

The total annual award is £65,000, comprising a £55,000 award (of which £5,000 is paid immediately upon acceptance of the offer and a further £15,000 can be drawn down during the BPTC year) and guaranteed earnings in the second six months of £10,000. Pupils are allowed to keep any earnings from their second six months, including any earned in excess of the £10,000 guarantee. New tenants have a guaranteed income of £240,000 (net of chambers’ expenses), in addition to their pupillage awards, over the first three years of practice.
