DHAKA: Ukrainian president Viktor Yanukovich has gone on sick leave with a respiratory ailment, his website said on Thursday, with the issue of a new prime minister still undecided.

‘The president of Ukraine has been officially registered as sick with an acute respiratory ailment and a high temperature,’ the web site said, reports The Straits Times.

Yanukovich’s prime minister Mykola Azarov resigned on Tuesday in the midst of mass street unrest and the president has yet to appoint a successor.

Serhiy Arbuzov, who was Azarov’s first deputy, has stepped in as interim prime minister.
