Aug. 7 (UPI) -- The far-right lawyer Abelardo de la Espriella was sworn in as president of Colombia Friday amid tight security at a ceremony held in the auditorium of a private university in Cali, the South American nation's third-largest city.

De la Espriella took an oath to "faithfully uphold the Constitution and laws of Colombia" as he received the presidential sash from Sen. Honorio Henríquez, president of Colombian congress and a member of the far-right Democratic Center party.

Once installed, the new leader then swore in his vice president, José Manuel Restrepo, while his guest of honor, 74-year-old farmer Luis Felipe Yagüé, looked on as a symbol of De la Espriella's support for small business owners and entrepreneurs, the Spanish news agency EFE reported.

The event triggered tight security measures, with 11,000 members of the security forces mobilized to ensure safety in Cali and the surrounding areas, local media reported. The strict measures included a ban on alcohol sales, transportation restrictions and reinforcements of the National Police.
