Shearer, however, can claim some mitigating factors. He confronted Jones immediately and directly after Yan, also known as Bill Liu, boasted in court that he had MP friends who would ensure he got citizenship. Shearer also conducted his own informal inquiry into the circumstances surrounding the approval. Key, in contrast, did not speak to Banks and instead only got his chief of staff to question him once the story started to get legs.
Shearer's position is made more difficult by there being no specific allegation of wrongdoing being levelled at Jones. That raises questions of fairness. Is mere innuendo sufficient for an MP to be stood down? How low do you set the bar?
In Banks' case, there is no argument that there were donations, leaving serious questions about their status and whether Banks was aware of them.
That said, the conjunction of citizenship approvals, claims of having mates in Parliament and political donations make for a nasty smell which needs the application of political disinfectant. Jones could make life a lot easier for Shearer and things a lot clearer if he explained exactly why he approved Yan's citizenship despite Yan being red-flagged by Interpol. Jones, however, is not commenting until Yan's trial on fraud charges is over.
That Shearer is understood to still be keeping his options open in terms of calling in some independent body like the Auditor-General to conduct an inquiry into the approval of Yan's citizenship suggests the Labour leader realises he is not on terribly strong ground in not standing Jones down, if only temporarily.
Shearer will simply have to take Key's criticism on the chin, put it down to experience and give thanks that Budget week means other matters are paramount and thus more likely to grab the public's attention.
