Wembley and Harrow were felt to be a natural match, and the London Borough of Harrow supported these proposals and called for a boundary rationalisation with Barnet so that the A5 Road (Watling Street) formed the enlarged borough's entire eastern boundary. Willesden was harder to satisfactorily match with a neighbour, with Ealing considered the most natural choice, the main problem being the lack of a focal point, with the industrial areas of Park Royal, Old Oak Common and North Acton forming a relatively ill-connected barrier between the two. The Commission concluded that there was insufficient justification for the disruption caused by the changes, and that such changes should only be considered during a comprehensive review of London's boundaries.
