Not erase, just add it to the already long list of suppressed and filtered content. Have you tried what I suggested, have you googled the names of few PMs? The page with search results for Churchill lacks the code to display photo in the bio at the right side. The layout and code is different, it's not just failing to load, cache problem or whatever.

The most likely explanation is that a google employee added the photo on a block list in support of BLM.

A (cache or whatever) problem that leads to the property not being set would produce exactly that result.

It also seems clear that there isn't one global list of these people and their portraits Google uses to feed these boxes: When I compare the screenshot someone posted below with what I see, many of the leaders have different portraits.

It would be an incredible coincidence that it's just him and right at this time. Also, from Google's support thread, he is receiving the same treatment as Weinstein, apparently Churchill was added to a list of people for whom Google won't show photo in the bio summary, next to Weinstein.
