"I am announcing my resignation in connect with the collapse of the coalition," said Yatsenyuk. He said Parliament could no longer do its work and pass necessary laws.
Of the group of legislators that took over after former President Viktor Yanukovich was ousted, two have pulled out: the nationalist Svoboda party and the Udar party (which is led by well known boxed Vitali Klitschko.) Yatsenyuk has been in office for just five months.
Oleksandr Turchynov, speaker of the parliament, has said Udar and Svoboda are responsible for finding a temporary prime minister until new parliamentary elections can be held.
