Cuban President Raúl Castro said on Saturday his government would prohibit the naming of streets or public monuments after his brother Fidel in keeping with the former leader’s desire to avoid developing a personality cult.

The younger Castro told a crowd gathered to pay homage to Fidel Castro in the eastern city of Santiago that the country’s National Assembly would pass in its next session a law fulfilling his brother’s desire that, “once dead, his name and likeness would never be used on institutions, streets, parks or other public sites, and that busts, statutes or other forms of tribute would never be erected”.

Fidel Castro, who died on 25 November aged 90, kept his name off public sites during his time in office because he said he wanted to avoid the development of a cult of personality. In contrast, the images of his fellow revolutionary fighters Camilo Cienfuegos and Ernesto “Che” Guevara have become common across Cuba in the decades since their deaths.

Raúl Castro spoke at the end of a second massive rally in honor of Fidel as Cuba neared the end of its nine-day public mourning. Castro’s ashes arrived on Saturday afternoon in Santiago, ending a four-day journey across Cuba that began after a rally in Havana’s Plaza de la Revolución.

Thousands of people welcomed the leader’s remains to shouts of “Fidel! I am Fidel!” Then hundreds of thousands gathered in Santiago’s Plaza de la Revolución on Saturday night, cheering speeches by the heads of state-run groups of small farmers, women, revolutionary veterans and neighborhood watch committee members.

The event was attended by the Bolivian president, Evo Morales, Nicaraguan leader Daniel Ortega and Nicolás Maduro of Venezuela, along with former Brazilian presidents Dilma Rousseff and Lula da Silva.

Castro’s ashes will be interred on Sunday morning in Santiago’s Santa Ifigenia cemetery, ending the official mourning period.

Mourning for Castro has reached peaks of near-religious public adulation across Cuba since his death, particularly in rural eastern Cuba. Huge crowds have been shouting his name and lining the roads to salute the funeral procession carrying his ashes from Havana to Santiago.
