Maybe, by asking WJEC to re-grade he put WJEC in a difficult position as they had to deal with English and Northern Irish regulators too. Now that he has instructed them, maybe it makes it easier for WJEC to negotiate with the English and N. Irish regulators as they don't have any choice in the matter - they have to regrade Welsh candidates' results. So maybe he wasn't being trigger happy. Maybe he was doing the right thing and perhaps he was wrong to publically ask them to look at regrading in the first place. Either way, I think the other countries' ministers and regulators are more in the wrong.
