LISBON - Portugal’s general election campaign ends on Friday for a vote that Prime Minister Luis Montenegro is expected to win but with no guarantee he can form a more stable government. Montenegro’s centre-right Democratic Alliance (AD) is tipped to win 32.5 percent of the vote, ahead of the Socialist Party (PS) on 26.5 percent, according to a poll of polls by Radio Renascenca. The recently formed far-right Chega (“Enough”) party could take 17.6 percent of the vote -- almost the same as it did in March 2024 elections -- to consolidate its position as Portugal’s third political force. Montenegro as a result risks finding himself again at the head of a minority government, caught between the PS, which was in power from 2015 to 2024, and Chega, with which he has refused to govern. Sunday’s election was called in March after the 52-year-old lawyer lost a vote of confidence in parliament following criticism that his consultancy firm created conflicts of interest. As such, “staying in power would already be a good result” for the prime minister, who took a “calculated risk” in the hope of strengthening his parliamentary seat, political commentator Paula Espirito Santo told AFP. Opinion polls appear to indicate an AD majority is unlikely but Montenegro could win the support of the Liberal Initiative party.
