BOGOTA: Colombian ex-president Alvaro Uribe will learn his fate Monday in a witness tampering case that saw him become the South American country’s first-ever former head of state to be put on trial.

The 73-year-old, who was president from 2002 to 2010, is charged with “bribery of witnesses” in a separate investigation against him, and risks a 12-year prison sentence in the highly politicized case.

The matter dates to 2012, when Uribe accused leftist senator Ivan Cepeda before the Supreme Court of hatching a plot to falsely link him to right-wing paramilitary groups involved in Colombia’s long-standing armed conflict.

The court decided against prosecuting Cepeda and turned its sights on his claims against Uribe instead.

Paramilitary groups emerged in the 1980s in Colombia to fight Marxist guerrillas that had taken up arms against the state two decades earlier with the stated goal of combating poverty and political marginalization, especially in rural areas.
