Singapore Prime Minister Lee Hsien Loong's People's Action Party scored a landslide victory in the country's general election held on Friday.

The ruling PAP won 83 out of 89 constituencies, while the opposition Workers' Party got only six seats in Parliament.

The People's Action Party, which has been in power since 1959, also improved its vote share compared with the last election, according to the DPA news agency. It got 69.86 percent of votes, a huge jump from the 2011 election's 60 percent - the lowest ever in its history.

"It is a good result for the PAP but it is an excellent result for Singapore," Lee Hsien Loong said in his victory speech on Saturday morning, according to AFP. Lee won the Ang Mo Kio parliamentary constituency with a comfortable margin.

"The result tonight will be noted by the outside world, by the media, by investors, by other powers and our neighbors. I believe these results will greatly bolster the confidence in Singapore and Singapore's future," he said, admitting that the results exceeded his party's expectations, according to Nikkei Asia Review.

The election results have stunned the opposition parties, which had contested in all seats for the first time in a bid to end PAP's domination in Singapore's politics, according to Malay Mail Online.

"You win, you lose. So I think that is part and parcel of life," Low Thia Khiang, leader of the Workers' Party, told reporters, according to AFP.
