Talk:1957 Beckenham by-election

Categories
I have started a discussion relevant to this article at Category talk:Elections in the London Borough of Bromley. My concern is that in 1965 Bromley did not exist and Beckenham was in Kent not London, so I think it is wrong for the article to be in Category:Elections in the London Borough of Bromley, Category:1957 in London and Category:By-elections to the Parliament of the United Kingdom in London constituencies.
