Ukraine's new interim government has been presented at Kiev's main protest camp, following last week's ousting of President Viktor Yanukovych.
Arseniy Yatsenyuk has been nominated as prime minister.
He told the BBC's Duncan Crawford the main challenge for the new government was to ''stabilise'' the country.
However he warned ''extremely unpopular steps'' would have to be taken because of Ukraine's financial plight.
