This document discusses different legal structures for social enterprises, including the Community Interest Company (CLS) and Public Limited Company (PLC). It notes that while the CLS structure is commonly used for commercial enterprises, it remains a popular vehicle for charities and social enterprises as a trading subsidiary or for joint ventures due to its flexibility. The PLC structure is also suitable, as demonstrated by examples of social enterprises that have adopted this structure, including Cafedirect PLC and The Ethical Property Company PLC.
