A TV spot claims the US president is trying to sway October’s presidential vote in favour of Lula’s far-right opponents

Luiz Inácio Lula da Silva’s presidential campaign has accused Donald Trump of wanting to “colonise” Brazil in order to capture its natural resources by meddling in next month’s presidential election.

The accusation came in a campaign advert that was published on social media on Thursday night by Lula’s team and will air on television on Friday amid growing fears over the impact alleged US interference could have on the vote.
