I doubt the wider family said anything but William and Kate May have decided they didn't want to be accused of being wheeled out to make everyone forget and getting the negative publicity
A lot of papers are mentioning Charles' role in the decision to give Andrew the boot. I wonder if he issued a kind of a 'family hold back' order to W&K just so that Andrew's public humiliation could be complete and unabridged, so to speak.
There have been reports over the years of disagreements between Charles and Andrew centering on the streamlining of the RF and resulting exclusion of the York family.
I wondered if BP under Charles' direction decided not to stop Andrew's boneheaded interview in hopes that he would be hoist with his own petard and all that would be left to do would be to see that the princesses didn't suffer from the inevitable fallout (which I understand from reports is a priority of BP).
