Ukraine has entered a new period of political uncertainty as from today the president has the right to call new elections because no government is in place. It follows an inconclusive election four months ago which left the country in a state of limbo. This morning parliament voted to call President Viktor Yushchenko to address the chamber on the situation.Yushchenko’s former ally, Yulia Tymoshenko failed in her bid to head a pro-Western coalition. The president is reluctant to nominate his rival, the pro-Russian Viktor Yanukovich as prime minister. His Regions Party topped the poll in March but not by enough to form a government on its own. The parliamentary speaker has said the body will defy any decrees by the president to dissolve it. With tensions mounting the country has returned to familiar scenes with supporters of both the main blocs taking to the streets.
