Far-right Chega party becomes main opposition in Portugal’s parliament

Party takes second place in election after overseas votes counted, overturning decades of bipartisan politics

The far-right Chega party has overturned decades of bipartisan politics in Portugal by squeaking into second place in the country's third snap election in three years, edging out the socialists to become the biggest opposition party in parliament.

The centre-right Democratic Alliance (AD), led by the prime minister, Luis Montenegro, finished first in the election 10 days ago, but once again fell well short of a majority, taking 31.2% of the vote and winning 91 seats in Portugal's 230-seat assembly. But the race for second place was a closely fought contest between the Socialist party (PS) and Chega.
