Sussex Police said Lewes bonfire societies committed no criminal offence by making tableaux of Scottish First Minister Alex Salmond.
Police received a number of complaints about the portrayal of Alex Salmond at the 2014 Lewes bonfire event on November 5.
They have since presented the complaints to the Crown Prosecution Service and it has been identified that no criminal offence occurred.
Police said effigies have long been a tradition at the annual event, with high-profile politicians and celebrities who have recently been in the news being featured in bonfire society processions.
“The event organisers have made it clear there was no intention to cause insult to anyone or any particular country by the choice of effigy: simply that the person chosen has been a popular media figure in the preceding 12 months.”
