Gustavo Petro says he will give a farewell address on July 20, calls for nationwide demonstrations and invites citizens to join the police parade as Parliament convenes that day.Abelardo de la Espriella narrowly won the runoff earlier this year, holds dual Colombian and United States citizenship, is backed by former US President Donald Trump and vows tougher crime policy, incentives for private investment and a 40% cut in public spending while pursuing prosecutions in United States courts.Iván Cepeda is organising resistance, threatens civil disobedience unless de la Espriella renounces dual citizenship or drops extradition plans, and Petro disputes the election result, plans legal challenges and will not leave office immediately.
