Ukraine's governing pro-Western coalition has lost its parliamentary majority after two members quit.
Ukrainian coalition loses majority
One was from PM Yulia Tymoshenko's bloc, the other from President Viktor Yushchenko's Our Ukraine party.
The coalition that first came to power after 2004's Orange Revolution now has 225 seats - exactly half of parliament.
It is unclear whether the coalition will remain viable, or whether it may become necessary to seek a new coalition or call elections.
The governing coalition can normally also count on the vote of one unaligned member, giving it a majority.
A spokesman for Ms Tymoshenko insisted the government would still be able to function.
