JAKARTA: Indonesia's upper house of parliament will pick the country's new vice president on December 2, its speaker said on Friday, after the dramatic resignation of Gibran Rakabuming Raka, the president's deputy and the son of his predecessor.

Gibran's resignation this week, which analysts say could widen the gulf between President Prabowo Subianto and former President Joko Widodo, followed a month of increasing political pressure from lawmakers after Indonesia's top courts ruled that he had inadequate education credentials to run for the job.

Speaker Ahmad Muzani said the upper house, which is tasked by law with appointing the new vice president, would now send a letter to Prabowo requesting that he submit two names for the job.
