The Czech president, Vaclav Klaus, has rejected a vote of no-confidence in Ukraine's prime minister, Viktor Yanukovych, passed by the country's parliament. Mr Yanukovych came first in Ukraine's presidential elections amid widespread allegations of voting irregularities. Mr Klaus said, however, the no-confidence vote would lead to increased instability in the country. He said he was worried about steps being taken which could lead to a "point of no return" in Ukraine. The Czech president has also called for a re-run of the disputed presidential election.
