According to a ‘news alert’ headline at the New York Times from four minutes ago (08.14 EST), Ukraine’s parliament has declared the election results invalid.
Nothing more at the NYT site (registration generally required, but you should be able to see the front page without it); it’s just the headline. Updates to follow as available.
Update (14.35 CET): Reuters reports that what the parliament has done is vote no confidence in the Central Election Commission, which a ‘large majority’ declared ‘had failed to fulfil its duties under Ukraine’s constitution and laws’.
Update (14.44 CET): Parliament’s resolution went a bit farther than that, actually, according to a brief Reuters report on the NYT site (reg. req.): it also expressly declared that the election was ‘invalid, subject to many irregularities and failed to reflect voters’ intentions.’
Update (15.39 CET): Well, maybe the election results are invalid. According to AP, parliament’s resolution will have legal force only if it receives President Kuchma’s assent. There’s a wild card still to be played, then. [Post title augmented to reflect uncertainty, though with hope the question mark may soon come back off.]
