In a previous thread there was discussion if Wikidata items without associated articles are permitted and makes sense. In the office-hour I asked Lydia to comment.

[18:49] <GerardM-> what is your opinion on items without links ... but items that are well linked to other items or complete a list  ?
[18:51] <Lydia_WMDE> GerardM-: they are fine imho. wikidata is covering more than wikipedia for example

So it is "officially sanctioned" we can and do have items in Wikidata that are not (yet) linked to any Wikipedia article. They will not be deleted when they link other items or when they include statements that show relevance/ notability.

Effectively we can add a presence for all members of the Lok Sabha and add links as and when they become available.
