Conor Murphy's calls for Northern Ireland Water to be re-nationalised will probably do more to feed the NIW story than quell it. The conspiracy theory from the beginning was that this was a contrived hit job to facilitate the minister's preference of bringing it back within the public sector. His actions will be viewed as confirmation that the theory has legs and encourage more digging. However, the evidence that has entered the public domain remains circumstantial. Also Murphy has two significant barriers to implement this proposal that are very good at killing off any idea - money and politics.
