Stormy political times likely lay ahead for Portugal after a general election delivered a minority government.

Only one minority government in Portugal has ever completed its four-year term. Their average life span is 14 months.

The center-right coalition government was re-elected in Sunday's ballot despite its unpopular austerity policies and on the back of an improving economy. But it will be outnumbered by left-of-center parties in the 230-seat Parliament where it is shy of a 116-seat outright majority. That means its further austerity measures and reforms risk being blocked.

With Portugal still recovering from its 78 billion-euro ($88 billion) bailout in 2011, the uncertainty could spell another bout of market jitters over the debt-heavy eurozone country.
