The foremost insolvency and restructuring chambers‘, South Square continues to impress with a host of silks and juniors involved in the most significant and thorny issues in the market. Multiple barristers from chambers have been involved in the high-profile collapse of supply chain finance funder Greensill Capital: Glen Davis KC leading Matthew Abraham acting for Credit Suisse Asset Management, and on the opposite side for the administrators, David Allison KC leads Ryan Perkins. Chambers has also been involved in key cases regarding CVAs, one of the most notable being Caffé Nero’s successful defence of its CVA, where they were represented by Tom Smith KC leading Henry Phillips, Adam Al-Attar appearing on the opposite side for the EG Group. Energy company administrations were a major feature of the 2021 workload too, and again members of chambers were a regular fixture in the most significant. In the case of Bulb Energy Limited, which at the time of its collapse was the UK’s seventh biggest electricity supplier, Mark Arnold KC acted for the proposed administrators, leading Richard Fisher KC and Henry Phillips.
