Flavio Bolsonaro has called himself the "leader of Brazil", despite losing the country's run-off vote to incumbent leader Luiz Inacio Lula da Silva.

The defeated candidate has flown to the US and thanked Donald Trump and "the wonderful American people for welcoming me".

The 45-year-old landed in Miami on Wednesday morning (local time) after travelling from South America on a private jet.

Mr Bolsonaro alleged that in Brazil there has been a "politically-motivated witch-hunt, intended to hold me hostage".

"Faced with the politicisation of the justice system in Brazil, I brought my family to the United States, where we are safe", the right-wing senator said.

He insisted he did not flee his country and left "so I could be the leader my people deserve".

And he said he would "lead the opposition from here".

Mr Bolsonaro made his comments in an open letter shared ⁠with journalists by his allies, Reuters reported.

He later deleted the letter, in which ⁠he called himself "president-elect ⁠of Brazil", ‌from social ‌media and quickly published a ⁠new ​document calling ​himself ​the "leader ⁠of Brazil".

Mr Bolsonaro said in the updated version: "I want to say, not only to my 60 million ​voters but to the Brazilian people, that I am the leader and that the criminals who stole Brazil's election ‌are part of a criminal organisation that has established a tyranny."

He did not give any evidence for the alleged electoral fraud. International observers ⁠have found Sunday's voting was fair.

Mr Bolsonaro has refused to concede following defeat to his rival, widely known as Lula, in the run-off vote and threatened to attempt to annul the election result.

He was ordered by Brazil's Supreme Court to surrender his passports ​to ​federal police as part of a probe into alleged money laundering, which he denies.

But he instead followed his father, jailed former president Jair Bolsonaro, who also fled to Florida after losing the 2022 presidential election to Lula.

Flavio Bolsonaro and his family crossed into Argentina via the Tancredo Neves International Bridge border crossing, before boarding a private flight bound for Ecuador, according to Argentina's migration department.

The senator appeared to be "distraught and fearful" of being arrested after his shock defeat became clear, news outlet O Globo said.

Lula won a historic fourth term in a surprise result that defied polls and he described reports his opponent had left the country as "shameful".

Voting was neck and neck throughout Sunday evening's count, before Lula, 81, pulled away to secure an unprecedented fourth term in office.

With virtually 100% of the vote counted, Brazil's electoral court said Lula had secured 51.79% of the ballots cast, to Mr Bolsonaro's 48.21%.

But Mr Bolsonaro refused to accept defeat and asked for the election results to be annulled after voting time had been extended by two hours by a supreme court judge. He said the extension was "unacceptable".

Mr Trump did ​not endorse Mr Bolsonaro ahead of the vote, but said on Monday the results "looked like another ‌rigged election" without providing evidence.

Lula's victory was all the more remarkable given that Mr Bolsonaro beat him by 2.2 million votes in the first round of the election earlier this month.
