Deletion of Results of the United Kingdom general election, 2017, by parliamentary constituency

Comment: I don't see that either  or  actually apply.  specifically allows spin-off articles with more detailed stats, giving Nationwide opinion polling for the United States presidential election, 2012 as an example.

Comment: This article passes . This guideline specifically states that:  Where statistics are so lengthy as to impede the readability of the article, the statistics can be split into a separate article and summarized in the main article. 650 constituencies is obviously lengthy so is not suitable for an article, but this is encyclopedic content as it is summarized fully in the main 2017 UK general election article
