LISBON (Reuters) - Portugal's opposition Socialists held a narrow lead over the ruling centre-right coalition in a poll published on Friday, which indicated the election race ahead of the Oct. 4 general vote remains in a technical draw.
The survey by pollsters Eurosondagem published in weekly Expresso showed the Socialists slipping 0.5 percentage points to 35.5 percent support and the ruling coalition down 1 percentage point at 34 percent.
The projected result was complicated by the fact that if the Socialists garnered that percentage of the vote they would win between 95 and 101 seats in the 230-seat parliament while the coalition would get between 99 and 102 seats, Expresso said. That would happen because of different weightings of electoral mandates across the country.
Analysts have warned that Portugal's election could bring political uncertainty because no one side is currently likely to win a full majority in parliament.
The poll was carried out between Sept. 11-16 and surveyed 1,510 people. The margin of error was 2.52 percentage points.
