The Democrats for a Strong Bulgaria (DSB) party will ask the parliamentary group of Democratic Bulgaria (DB) to request a hearing for prime minister Rumen Radev in parliament, the DSB press office said.

The request concerns the position Bulgaria took in Dublin on the French declaration on key principles of European security. The declaration cites Russia's aggression against Ukraine and confirms NATO as the basis of shared security.

DSB says Bulgaria's position came out in three versions in a single morning: that the country had not signed, that it had signed, and that it had signed "with reservations". The party claims Bulgaria is the only EU country that has split from the joint declaration.

DSB calls the security policy of the Radev cabinet dangerous improvisation. It says such wavering shows incompetence and threatens national security.

Bulgaria has reservations only about the preamble and supports the declaration, Radev told reporters in Dublin. The prime minister said Sofia wants the texts to follow the peace talks on Ukraine that have begun, and the wording not to limit dialogue and possible solutions.
