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.

With just four seats left to assign, the center-right Democratic Alliance had secured a 32.7% share of the vote, which means the party is short of a full majority. It is the third election in as many years in Portugal.

Portugal’s third general election in three years has failed to deliver the result that could break the worst spell of political instability for decades in the European Union country of 10.6 million people.
