Thousands of anti-government protesters in Bulgaria — some chanting "Mafia out" — have hit the streets of the capital Sofia.
They allege endemic corruption and want the resignation of PM Boyko Borisov, his centre-right government and the chief prosecutor.
Governance watchdog Transparency International ranks Bulgaria as the most corrupt of the 27 nations in the EU.
So, what's the story behind the protests? And, can Borisov successfully calm the storm engulfing his administration?
Borisov reiterated he would stay in office until his mandate expires on March 2021 though he would not seek a new term.
