New Era Party
Kalvītis was the first prime minister in the history of post-soviet independent Latvia whose government was reelected by an election in 2006. New Era Party, however, weakened, so a coalition reshuffle took place, and a 4-party centre-right coalition emerged. The government lasted only until 5 December 2007, when Kalvitis resigned due to his continuous and unsuccessful attempts to dismiss Aleksejs Loskutovs, the head of KNAB, the State Anti-Corruption Agency, after Loskutov's had investigated shadowy matters of the PM's party.
