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.

Portugal's governing right-of-centre Democratic Alliance has won snap parliamentary elections - the third in as many years - again falling short of a majority. Its leader Luís Montenegro promised supporters to "stimulate investment" and to "guarantee prosperity and social justice".

Voters in Portugal went to the polls Sunday for the country's third general election in three years, with Prime Minister Luis Montenegro tipped to win, but without an overall majority.Final opinion polls suggested his centre-right Democratic Alliance (AD) was ahead of the Socialist Party (PS) and set to pick up more votes than in the last election in 2024.
