Political tensions in Venezuela are set to rise on Sunday with the opposition holding a public vote to undermine President Nicolas Maduro and his controversial bid to rewrite the constitution. The symbolic "plebiscite" will take place after nearly four months of violent protests against Maduro, during which nearly 100 people have died.
