Indonesia's vice president resigns amid signs ruling alliance is fraying

Indonesia's Vice-President Gibran Rakabuming Raka has submitted his resignation, an aide has told the BBC, in a move which could further strain the political alliance that helped propel President Prabowo Subianto to power.

It comes after Indonesia's Supreme Court ruled that a high-school document used during Gibran's 2024 election campaign was invalid.

The ruling prompted more than 100 lawmakers to support a parliamentary initiative that could have paved the way for proceedings to impeach Gibran.

The aide, Budi Arie, said Gibran's resignation letter was submitted directly to Prabowo on Wednesday. It remains unclear if it has been accepted.

Gibran has long faced controversy over whether his high school qualifications met legal requirements to run for office.
