So this is one of those examples of fake news created by either an innocent misunderstanding of a badly written photo caption or a deliberate attempt to mislead - and as all reports seem to lead back to Celebitchy I’d lean towards the deliberately malicious.
Camilla didn’t stay in the car during this trip not even for a short time. She was a couple of minutes behind Charles getting out.
The photo in question was either snapped just before she got out or at another point on that trip.
Here’s how the confusion happened as far as I can see.
The Kenyan news site posted the picture of Camilla in the car with a caption which was something like ‘Camilla seen in car during King’s visit to Uhuru Gardens’
The caption means ‘at some point during the visit she was pictured in the car’
That sentence - again just a picture caption not a report - has been taken to mean that she stayed in the car ‘during the whole visit’ - it was compounded by a following photo showing the King paying tribute without Camilla but the video footage shows that she was simply waiting alongside a little ways back with the First Lady while that ceremony happened.
The only sites ‘reporting’ on this ‘incident’ are the gossip site and some of those weird ‘scraper’ sites like geo news which just copy and paste stuff which might get clicks from anywhere on the internet without checking.
So @Estermay there was no Kenyan journalist reporting this incident because it did not happen.
