Ukraine's parliament Thursday confirmed the appointment of pro-Western speaker Volodymyr Groysman as premier in a bid to end months of political gridlock and unlock vital aid to the war torn-state.

Lawmakers voted by 257 to 50 to approve the resignation of Prime Minister Arseniy Yatsenyuk -- condemned by President Petro Poroshenko for losing the public's trust -- and select Groysman in the first cabinet overhaul since Ukraine's 2014 pro-EU revolt.
