Симеон II
In 2001, the former monarch of Bulgaria Simeon Saxe-Coburg-Gotha returned to power, this time as Prime Minister with his National Movement Simeon II (in Bulgarian abbreviated: NDSV), having won half (120) of the seats. His party entered a coalition with the DPS and invited two functionaries of the BSP (who sat as independents). In opposition were the two previously governing parties - the Socialist Party and the Union of Democratic Forces. In the four years in opposition the SDS suffered the defection of numerous splinter groups. The ruling party NDSV itself ruptured into a pro-right core and a pro-liberal fringe group. Bulgaria entered NATO in 2004.
