Jair Bolsonaro, Brazil’s president, issued the stark warning after claiming he was working with his counterparts in the US to sow dissent within the Venezuelan Army. Venezuela is in turmoil after months of rowing between Maduro and opposition leader Juan Guaido. Mr Guaido is seen by most in the world as the country’s actual leader, with many alleging Maduro gained his presidency by fraudulent methods.
During an interview with Jovem Pan radio, Mr Bolsonaro said if there was a military invasion in Venezuela, he would ask Brazil’s National Defence Council and Congress what action would need to be taken.
He said “We cannot allow Venezuela to become a new Cuba or North Korea.”
Mr Bolsonaro added that he believe Maduro’s backers would fight in his honour if his power was taken away.
Once again thousands of Venezuelans took to the streets on Saturday to protest against Maduro’s reign.

Anger has been consistently directed at Maduro, who has in the past refused to accept humanitarian aid from other countries despite crumbling healthcare and harsh living conditions for many of his citizens.
Venezuelans waved placards in the country’s capital Caracas as they rallied together against ongoing blackouts and food shortages.
Anger against Maduro has mounted in recent days after the socialist dictator imposed a 30-day rationing of electricity.
Guaido, who declared himself interim president in January, earlier encouraged his supporters to demonstrate against Maduro’s government.
He was stripped of his parliamentary immunity last Thursday meaning he could face arrest.
Mr Guaido, the head of the National Assembly party, is now recognised by more than 450 nations as the country’s legitimate leader.
But his efforts at getting humanitarian aid into the country have so far failed.
Maduro receives backing from its international allies Russia and China.
