The Democratic Alliance led by Montenegro, comprising center-right factions, initially emerged as the frontrunner in the 2024 election but only managed a meager 29% of the vote, failing to secure a majority. The Socialist Party trailed closely while the far-right Chega party captured significant support, making consolidation of a stable governing coalition a challenge for Montenegro. The recent controversy concerning Montenegro's family business dealings, particularly a real estate and consulting firm with ties to a casino operator, has intensified scrutiny and called into question the integrity of his leadership. Despite Montenegro's claims of having handed over his business interests to his wife, the opposition's allegations of ethical violations have proven detrimental to his government, culminating in the latest no-confidence ballot.

In the wake of the government’s ousting, both the Socialist Party, which previously held power, and the Chega party might stand to gain from the fallout. However, both have faced their share of controversies, including scandals involving party members that threaten their reputations. Following the resignation of former Prime Minister António Costa amid investigations into potential government misconduct, the political arena in Portugal is shaping up for a contentious electoral battle as citizens await the upcoming elections.
