Election: General election expected in September or October
Backdrop: Portugal's centre-right coalition, elected in 2011, imposed painful austerity as part of its bailout. But the economy is growing again, helping Lisbon to last May exit the bailout. Unlike Greece and Spain, Portugal has not seen the rise of an anti-austerity party.
Key election themes: Still, the impact of austerity measures, economic reforms are expected to be key themes. Corruption scandals are also a source of discontent.
Expected outcome: A survey of voting intentions by Eurosondagem pollsters published in late February showed the coalition with 35 percent support, with centre-left Socialists, on 37.5 percent. This puts Portugal in the camp of elections this year that may be too close to call.
Wild Card: Whether the ruling coalition, made up of the Social Democrats and smaller rightest CDS-People's Party, run together or as two separate parties could determine the outcome of this election, analysts say.
Expert View: "Although the socialists are likely to win the elections, the outlook for government formation remains very uncertain," Antonio Roldan Mones, an analyst at Eurasia Group, said in a note. "This is because of a number of variables, the most important being whether the Social Democrats and the CDS-People's Party decide to run together or on separate lists. In the likely event they run on a single list, the election will be tight, but neither side will have an absolute majority."
