Wikipedia:Articles for deletion/Irexit
that we have parallel articles Dutch withdrawal from the European Union, Greek withdrawal from the eurozone and Frexit dealing with a mooted French withdrawal.   does not prohibit mention of parallel articles.   Such articles exist even though ideas like Partition and secession in California may never go anywhere, because the secession discussions are inherently notable, and in the specific case of Ireland, good sources exist.  On the quesiton of the best name for the article, we can punt to the article's talk page.  It is the topic itself that is notable
