United Co-operatives has purchased the 19-store Leathleys Quality Fare group for an undisclosed sum.
The group, which is based in the north east and Yorkshire, had an annual turnover of £38m and was ranked 31 in The Grocer Top 50 of independent stores.
The deal takes the co-op society above 500 stores and follows just two weeks after it acquired the 12-store chain Cheers Shropshire, which was ranked 49 in the Top 50.
In April United chief executive Peter Marks said he planned to spend £100m on acquisitions in the financial year to January 2005, ad the latest deal has taken the total spent to more than £50m.
