Belarus changed its entry because of voting fraud in their selection contest...Lukashenko "took firm actions againt irregularities to preserve the justice". Really, it has been reported as such. Almost hilarious considering the individual involved
"Took firm actions againt irregularities to preserve the justice" probably means that he massively rigged the contest so that the outcome suited his personal preferences.
The band they chose after getting rid of the previous winner has an Italian guy in it. The chap has been summoned to meet Lukashenko. Not sure if he came back...
