Castillo called on his supporters to be vigilant and defend each vote from possible foul play.

“We must be vigilant to defend the democracy that is expressed in each of the votes, inside and outside our beloved Peru. We can't rest. May this historic vigil pave the way for the rebirth of a new country,” Castillo tweeted.

Cumplimos con nuestro deber ciudadano. Los invito a que también nos apoyen como personeros para defender el voto popular en las urnas. Seguimos adelante. #PalabraDeMaestro #Elecciones2021 pic.twitter.com/XoxRJdgN4m
