Rightist opposition party Democrats for Strong Bulgaria (DSB) started preparing a no-confidence motion against the government, regarding the crisis in the healthcare sector, DSB leader Ivan Kostov said.

DSB will search approval from other opposition parties for collecting signatures and tabling the no- confidence vote, Kostov said as quoted by Bulgarian news agency (BTA).

Kostov said that DSB would also support a no-confidence vote regarding the government's energy policy and the social and security policy if they were separated.

Leader of DSB's national movement, Stoicho Katsarov said that the party has already tried all possible means to influence the government regarding the healthcare crisis, but their efforts were without result.

Kostov will send letters to the leaders of all parliamentary groups, suggesting a declaration, which will support the right of Bulgaria to defend its national interests.
