Portugal’s president was due to convene the country’s political parties for consultations on Monday, after a general election delivered another minority government as well as an unprecedented showing by populist party Chega (Enough) that added momentum to Europe’s shift to the far-right.

Portuguese political parties were wrapping up their campaigns on Lisbon's streets on Friday ahead of a general election on Sunday - the country's third early vote in as many years - that polls indicate is unlikely to yield a stable government.

Voting began Sunday in Portugal's snap elections, the third in less than four years, to elect a new government. Voters will cast votes to elect 230 seats, which were allocated in 22 constituencies by the election system that is the d'Hondt method -- appointing seats in parliament among federal states or in proportional representation among parties.
