Dingle disappears, soon to reappear?

On the eve of a plebiscite, the good burghers of Daingain, formerly good burghers of Dingle look like they may swing it back again tomorrow. The last word lies with the Minister, but if the result is decisive enough, a compromised change may be inevitable. Hmmm… is there a lesson for others attempting to return place names to the ‘genuine original’?
