The so-called Flag of Ireland should be removed from this article. It is not a symbol of Northern Ireland. A group of organised Irish-republican POV editors is insisting on retaining the image here, presumably for political reasons. They also insist on naming it "Flag of Ireland", despite the obvious ambiguity and political implications of doing so in this article. The flag was stable as "Irish tricolour", which matches the text and is consistent with the names of the other flags ("Union Flag" and "Ulster Banner"), but a renewed campaign by the POV editors has imposed their will by force of numbers. This kind of oppressive behaviour is going to drive other editors away.
