The former Yugoslav republic of Montenegro has been an independent state for just six years.
Its ruling coalition led by the Democratic Party of Socialists campaigned for Sunday’s parliamentary election on the premise that freedom from neighbouring Serbia was still under threat.
The centre-left alliance headed by former prime minister and president Milo Dukanovic is expected to be re-elected.
Opinion polls suggest their grouping will win 47 percent versus 24 percent for opposition parties led by Liodrag Lekic.
Whoever wins will oversee talks on Montenegro joining the EU.
The DPS has been the dominant political force for more than two decades. But it has been dogged for years by allegations of cronyism and corruption and will face intense scrutiny from Brussels.
It could still be years before the country receives final approval.
