In July 1940, after receiving the 35th Infantry Brigade from the recently disbanded 12th (Eastern) Infantry Division, the division was reorganised as a standard infantry division and later in the year, on 18 November, the division was redesignated and converted into the 56th (London) Infantry Division and, on 28 November, the brigade was renumbered again as the 167th (London) Infantry Brigade. In the same month the 1st Battalion, London Irish Rifles was transferred to 168th (London) Infantry Brigade and was replaced by 15th Battalion, Royal Fusiliers, a hostilities-only battalion raised only a few months before, making the brigade, temporarily, an all-Royal Fusiliers brigade. However, the 15th Fusiliers were posted elsewhere in February 1941 and replaced by 7th Battalion, Oxfordshire and Buckinghamshire Light Infantry, a battalion created in September 1940, by the redesignation of 50th (Holding) Battalion.
