South Africa's parliament descended into chaos as MPs were forcibly removed after heckling President Jacob Zuma over corruption allegations.
The unprecedented sign of discontent at his administration came as the leader delivered his first annual State of the Nation speech since his re-election last May.
It had been billed as a chance to highlight the achievements of the ruling African National Congress (ANC) and its plans for the year ahead.
But firebrand former ANC youth leader Julius Malema led the hostile reception from the far-left Economic Freedom Fighters (EFF), who began challenging Mr Zuma about the claims.
Interrupting his speech, the MPs demanded to ask the president about when he would repay part of a £15m state-funded security upgrade of his rural home.
Speaker Baleka Mbete warned several EFF mmbers to sit down before ordering they be removed by security officers, prompting a brief brawl in which several people were injured.
Mr Malema, whose T-shirt was torn in the fracas, said: "We have seen that we are part of a police state."
MPs from the main opposition Democratic Alliance (DA) also left the chamber.
Mr Zuma then delivered his speech to claps and cheers of support from ANC lawmakers as he highlighted progress made by South Africa since the end of white-minority rule two decades ago.
The president has suffered a dip in popularity after what was seen as extravagant spending on his rural home at taxpayers' expense - and as the country's economy has slowed sharply.
DA parliamentary leader Mmusi Maimane said Ms Mbete's decision to call in security officers undermined democracy in South Africa, evoking Nelson Mandela long struggle to acheive it.
"She cannot escalate the issue by sending police into the chamber," Mr Maimane told reporters outside parliament.
"It robs the people of South Africa of what President Nelson Mandela fought for, which is the upholding of the rule of the law and the constitution."
