embsky announced the decision less than an hour after the Duma rejected Kiriyenko at the first try. Under the constitution the president must dissolve the Duma if it rejects his candidate or candidates for prime minister three times. Earlier on Friday 143 deputies voted for the prime minister-designate and 186 votes rejected him. Kiriyenko needed at least 226 votes to be confirmed in the post. Parliamentary sources said Yeltsin's new request was expected to be delivered to the Duma speaker Gennady Seleznyov later on Friday and the communist-dominated chamber will then have one week to consider it. Yeltsin sacked former prime minister Viktor Chernomyrdin and his entire government on March 23 and named Kiriyenko, a 35-year-old former banker, to form a new cabinet. Yeltsin has warned his opponents, who say Kiriyenko is too young and inexperienced for the job, that he is ready to dissolve the chamber and call an early parliamentary election if they do not approve his candidate.
