[1] In practical terms, this means it encompasses teams from North and West London.

The MCCL was officially founded in 1972, after holding a 'dry run' in 1971 to ensure that the league's launch went smoothly.

[3] It was founded with 16 clubs as members (Brentham, Brondesbury, Ealing, Edmonton, Enfield, Finchley, Hornsey, North Middlesex, Richmond, Shepherds Bush, South Hampstead, Southgate, Stanmore, Teddington, Wembley, and Winchmore Hill), and in the first season Hornsey won the league title with ten wins from their fifteen fixtures.

[4] Nine of the ten clubs who are expected to play in the Premier Division in 2024 were among these founder members.

The MCCL has undergone two major mergers in recent years, merging with the 1987 League in 2019, and then subsequently absorbing the Middlesex Championship ahead of the 2021 season.
