Despite the BBC patriotically insisting that Prince Philip looked spry at yesterday's coronation commemoration ceremony, the Royalist thought that the patriarch of the House of Windsor, who turns 92 on Monday, undoubtedly looked unwell.
There was clear concern etched on the faces of the Queen and other members of the family as well.
And the specualtion that Philip's health may be failing faster then the palace is letting on intensified after it was revealed he passed on yesterday's evening celebrations, and had missed several engagements in the days before the service.
And today Peter Philips, his grandson (via Princess Anne) stirred yet more speculation when he was asked in an interview on breakfast TV in the UK if Prince Philip was feeling 'under the weather' and replied: "Yes, but you also have got to remember his age, both of their ages, you know... what they do at their age - they do a lot more than most other pensioners of their equivalent age so... if occasionally there is the odd engagement cancelled, it shouldn't come as such a surprise, given the workload that they do have."
It shouldn't come as a surprise, of course, but the fact that it is Peter who delivered the news does.
