The adverts may have reached as many as 400,000 people - despite appearing to break several of Facebook's policies and mark the first time that the prime minister's image has been doctored in a systematic way en masse.
More than £12,929 was spent on 143 adverts, which originated from 23 different countries including the US, Turkey, Malaysia and the Philippines.
They included one with faked footage of a BBC newsreader, Sarah Campbell, appearing to read out "breaking news" that falsely claimed a scandal had erupted around Sunak secretly earning "colossal sums from a project that was initially intended for ordinary citizens".
They carried the untrue claim that Elon Musk had launched an application capable of "collecting" stock market transactions, and followed with a deepfaked clip of Sunak saying the government had decided to test the application rather than risking the money of ordinary people. The clips then led to a spoofed BBC News page promoting a scam investment.
