Portugal’s far-right Chega party eyes kingmaker role as country goes to polls

Election triggered by resignation of PM Antonio Costa could see scandal-hit Socialist party ousted by rightwing coalition

The Portuguese left and right are braced for a tight race as the country votes in its second snap general election in three years, a closely fought contest that is also expected to result in huge gains and a possible kingmaker role for the far-right Chega party.

Sunday's election was triggered by the collapse of the socialist government of Antonio Costa, who resigned as prime minister in November amid an investigation of alleged illegalities in his administration's handling of large green investment projects.
