The BBC on Thursday fired radio presenter Danny Baker for a tweet about the Duke and Duchess of Sussex's baby.
The post, which has now been deleted, showed an image of a couple holding hands with a chimpanzee, which is dressed in clothes, alongside the caption: "Royal baby leaves hospital".
It drew criticism for making fun of the Dutchess' heritage — her mother Doria Ragland is African American.
Executives were cited on the BBC News' website as saying he showed a "serious error of judgement".
Baker labelled the tweet an "enormous mistake, for sure," adding: "Anyway, here's to ya Archie, Sorry mate."
"Would have used same stupid pic for any other Royal birth or Boris Johnson kid or even one of my own. It's a funny image. (Though not of course in that context.)" he wrote.
The 61-year-old later labelled the decision to fire him a "masterclass of pompous faux-gravity" and said it was his "turn in the barrel".
Baker presented a weekend show on BBC Radio 5 Live for which he won a Sony Gold award for Speech Radio Personality of the Year three times and a Gold Award for entertainment show of the year.
Meghan, wife of Prince Harry, gave birth in the early hours of Monday morning to a baby boy, Archie, the first mixed-race child to be born into a senior position in British royalty in recent history.
