SINGAPORE - Singapore's president has dissolved the city-state's Parliament, signaling a general election could be coming within weeks.

President SR Nathan announced in the government gazette Tuesday that parliament was dissolved and a general election would be held within three months. The move was based on advice from Prime Minister Lee Hsien Loong.

Political parties must announce their candidates between five days and one month after Parliament is dissolved, and polling is held between 10 and 56 days after that.

In the last three general elections, voting was held about three weeks after parliament was dissolved.

The ruling People's Action Party was been in power since 1959.
