Portugal's far-right Chega becomes main opposition party

Portugal's far-right, anti-establishment party Chega has overtaken the centre-left Socialists to become the main opposition party for the first time after the final tally of ballots from abroad in a snap parliamentary election.

The centre-right Democratic Alliance of Prime Minister Luis Montenegro won 91 seats in the 230-seat single-chamber parliament, including two from out-of-country voting, after the 18 May vote.
