Parliament speaker Mihaela Dotsova should resign, her deputy Atanas Atanasov said on Facebook after a reporter was hurt in an incident, the press office of Democrats for a Strong Bulgaria said.

Atanasov said a journalist was subjected to an unacceptable attack and suffered bodily harm in front of Dotsova, and she showed no human reaction.

"Such callousness and inhumane conduct is incompatible with the post of speaker of parliament," he wrote.

Earlier today, the National Protection Service (NSO) ordered a check on the actions of the security staff who were involved in the incident. NSO officers and a representative of the PIK news agency were caught up in it. It happened at an event attended by people under the service's protection.
