Right-wing former Senator Mario Abdo Benítez has been sworn in as the new president of Paraguay after defeating his liberal rival in April elections.

Mr Abdo Benítez is the son of a close aide to ex-military dictator Alfredo Stroessner, and has faced criticism for defending the former leader's record.

He replaces Horacio Cartes. Both are from the conservative Colorado Party.

The 46-year-old says he will take a law-and-order stance and implement business-friendly policies.

Paraguay has enjoyed strong economic growth in recent years.

Gen Stroessner ruled the country from 1954 to 1989 and is viewed by critics as one of Latin America's most secretive and sinister dictators.

The new president has recently tried to distance himself from his father Mario Abdo Sr's political background, saying that he wants to be called by his nickname rather than the first name that he shares with his late father. "I am not the son of... I am Marito," he said.

However, media in Paraguay noted that he drove to his inauguration in a white Chevrolet used by Gen Stroessner to attend military parades.

The car belongs to Mr Abdo's family and has been used by other presidents following the return to democracy, including his predecessor, Horacio Cartes.
