Middlesex 4 was an English level 13 Rugby Union league with teams from north-west London taking part. Promoted teams moved up to Middlesex 3 and since the cancellation of Middlesex 5 at the end of the 1991âÂÂ92 season there was no relegation. The division was cancelled in at the end of the 1995âÂÂ96 campaign after nine seasons due to the merger of the Hertfordshire and Middlesex regional leagues.
When the division was created in 1988 it contained the following teams:
The original Middlesex 4 was a tier 11 league. Promotion was up to Middlesex 3 and relegation was down to Middlesex 5.
The creation of Herts/Middlesex at the beginning of the 1992âÂÂ93 season meant that Middlesex 4 dropped to become a tier 12 league. The introduction of National 5 South for the 1993âÂÂ94 season meant that Middlesex 4 dropped another level to become a tier 13 league for the years that National 5 South was active. Promotion continued to Middlesex 3 but the cancellation of Middlesex 5 at the end of the 1991âÂÂ92 season meant there was no longer relegation. The merging of the Hertfordshire and Middlesex regional divisions at the end of the 1995âÂÂ96 season meant that Middlesex 4 was cancelled.
