Voters in Cambodia are casting ballots in the country's general election on Sunday. Due to the absence of a strong opposition party, Prime Minister Hun Sen's Cambodian People's Party is almost certain to win.

Candidates from 18 political parties are running in the first general assembly election in five years.

Hun Sen and his wife cast their ballots at a polling station near Phnom Penh, surrounded by a crowd of reporters.

A court decision forced the largest opposition Cambodia National Rescue Party to dissolve ahead of the election in 2018. The ruling party subsequently took all 125 seats in the assembly.

In May of this year, electoral authorities disqualified the main opposition Candlelight Party from the election. They claimed the party's paperwork was incomplete.

Opposition leaders who fled the country are calling on supporters to boycott the election or cast invalid ballots.

Polling stations across the country will close at 3 p.m.
Preliminary results are expected to be announced in the evening.
