outer borough of London, on the northwestern perimeter of the metropolis. It is part of the historic county of Middlesex. Edgware Road, on the line of the Roman Watling Street, forms its eastern margin. The borough includes such areas as (roughly from north to south) Queensbury, Kenton, Preston, Kingsbury, Neasden, Sudbury (in part), Wembley, Cricklewood, Willesden Green, Stonebridge, Willesden, Alperton, Brondesbury, Kilburn, Harlesden (in part), and Kensal Green. Brent was formed in 1965 by the amalgamation of Wembley and Willesden (both in the former Middlesex county). It is named for the small River Brent, a tributary of the River Thames that formed the boundary between the former boroughs of Wembley and Willesden. Within the borough are Victorian and later residential suburbs, industrial areas, office centres, and immense tracts of railway land
