Progressive voters and supporters of incumbent president Luiz Inácio Lula da Silva left reeling after far-right surge

Flávio Bolsonaro is in pole position to win Brazil’s presidential election, after a far-right tsunami propelled him to a shock first-round victory over the incumbent, Luiz Inácio Lula da Silva, leaving progressive voters reeling.

The 45-year-old rightwing candidate received 56.1m votes to Lula’s 53.8m – 47.03% to 45.16% – meaning the 80-year-old leftwinger has a mountain to climb if he is to bounce back in the second round on 25 October. Never, since the return of democracy to Brazil in 1985, has the first-round runner-up managed to turn the game around and win the second ballot.

“Miracles are possible in politics. But I don’t see that happening,” the political scientist Miguel Lago said of Lula’s chances of snapping back. “I don’t see Flávio losing this election now.”
