Anti-government protesters blocked polling stations and forced about one in 10 across Thailand to close, raising questions about the legitimacy of the election.

Voting ended at 08:00 GMT on Sunday but no results will be announced.

About 89 percent of polling stations were able to operate normally, according to the country's election commission.

Polls are scheduled to re-open again within the next few weeks.
