Portugal’s ruling center-right Democratic Alliance (AD) won a snap parliamentary election on Sunday but again fell short of the majority needed to end a long period of instability as the far-right Chega gained a record share of the vote.

The incumbent center-right Democratic Alliance won Portugal’s general election Sunday, official results showed, but it fell short of a majority in Parliament and was set to take office as a minority government.

Portugal is a parliamentary republic with a unicameral legislature of 230 members, elected by direct vote to serve four-year terms. On March 13, President Marcelo Rebelo de Sousa dissolved parliament and called a snap election for May 18, marking the country's third early parliamentary election in less than four years.
