Political crisis and Covid surge in Brazil rock Bolsonaro

Brazil's Jair Bolsonaro is facing the biggest crisis of his presidency after the heads of the army, navy and air force all quit and the country recorded its highest Covid-19 daily death toll.

The unprecedented resignation of the defence chiefs is being seen as a protest at attempts by Mr Bolsonaro to exert undue control over the military.

Mr Bolsonaro's popularity has plummeted over his response to Covid-19.

Nearly 314,000 people have died, with a new daily record of 3,780 on Tuesday.

There have been more than 12.5 million confirmed cases.

Brazil's far-right president, who came to power two years ago, has consistently opposed quarantine measures, arguing that the damage to the economy would be worse than the effects of the coronavirus itself.

He has also told Brazilians to "stop whining" about the situation.

On Monday, the president was forced to reshuffle his cabinet after his foreign and defence ministers both quit.
