KFC's ad featuring a chicken dancing to a rap soundtrack as it headed to slaughter was the most complained-about advert of 2017.
The Advertising Standards Authority (ASA) attracted 755 complaints among them were claims it was disrespectful to chickens and distressing for vegetarians, vegans and children.
However, the ASA decided not to ban it, ruling that it was unlikely to cause distress or serious or widespread offence, as there were no explicit references to animal slaughter.
