Final campaign events are underway in Brazil as candidates Luiz Inacio Lula da Silva and incumbent leader Jair Bolsonaro make their last pitches to voters ahead of Sunday's crucial presidential election.

Recent polling data indicates that Lula maintains an advantage over Bolsonaro, though that margin has decreased. Analysts suggest it is unlikely either contender will secure enough backing to claim an outright victory in the initial round of voting.

Additional information regarding the final electoral preparations and updated polling figures is anticipated as the story continues to unfold.
