Ukraine's prime minister Arseniy Yatsenyuk quits

Ukraine’s prime minister, Arseniy Yatsenyuk, announced his resignation on Sunday following a political crisis that has paralysed the government and frozen the release of vital western aid for months. “Having done everything to ensure stability and make a smooth transition of power possible, I decided to step down from the post of prime minister of Ukraine,” the 41-year-old pro-western leader said in a video address. His decision comes barely two months after he survived a no-confidence vote in his government.
