East Timor President Jose Ramos Horta is facing elimination in the first round of the country's presidential elections.
With more than 50% of votes counted, Mr Ramos Horta trailed in third behind opposition leader Francisco Guterres and former guerrilla leader Taur Matan Ruak (known as "TMR").
The top two candidates face a run-off in mid-April.
Mr Ramos Horta was a key figure in East Timor's struggle for independence.
Twelve candidates in total are taking part. Full provisional results are expected to be announced on Monday.
Mr Ramos Horta won in the second round against Mr Guterres in 2007 after coming second in the first round.
The presidency is a largely ceremonial role, but the election comes in a year of security transition, with UN forces scheduled to leave by the end of the year.
East Timor gained independence in 2002 after three years of UN administration, which followed more than two decades of bloody guerrilla warfare during Indonesian rule.
