The speaker referred to 'HM the King and HM the Queen, which is incorrect as it is HM Queen Máxima.
Is that so? I thought it was only "the queen" as there is only one at the moment? Beatrix reverted back to her title of princess, so there is no need to distinguish between two queens. Such a problem only arises when there is a dowager queen and the wife of the reigning king, so there is a need to make a difference. But even then Maxima as the wife of the reigning king would be the queen, no?
