Rio carnival: Samba school wins with anti-corruption message

This year's Rio Carnival has been won with a lurid attack on social ills and corruption in Brazil.

The Beija Flor school showed the country with a huge rat in charge, while politicians were seen holding briefcases lined with gold.

Beija Flor beat 12 other schools to win the top prize at the carnival for a 14th time. Preparations for the parade begin months in advance.

Entrants in the competition often adopt a political theme.

The second-placed school also criticised Brazilian leaders in their entry, depicting President Michel Temer as a vampire.
