Today's parliamentary sitting was cancelled due to a lack of quorum, a direct result of GERB leader Boyko Borisov's declaration.
Borisov's anger was reportedly sparked by GERB's poor performance in the partial local elections for municipal councillors in Pazardzhik.
The Bulgarian Socialist Party (BSP) responded to Borisov with a written statement stressing that a new political crisis would have a destructive effect on social stability and key systems in the country.
Prime Minister Rosen Zhelyazkov called off the scheduled government meeting, while many GERB MPs had travelled to their constituencies to meet with voters.
