I’ve been trying to get the point across for years: Peru does not have a (pure) presidential system. It is a semi-presidential system.
Peruvian Prime Minister Ana Jara was forced to step down after losing a vote of confidence in Congress on Monday… President Ollanta Humala must now select a new prime minister and cabinet.
Via the BBC. My emphasis.
Also, “It is the first time in half a century that Peru’s Congress has deposed a prime minister.” But not using a power does not mean the power does not exist–and, potentially, affect the political process.
