There have been scuffles between police and protesters in Madrid amid demonstrations over a corruption scandal which has embroiled the Spanish Prime Minister Mariano Rajoy.
It had started peacefully in front of the ruling People’s Party headquarters but degenerated after midnight. Several people including police officers were injured. At least one person was detained.
Similar trouble was also reported in Valencia.
The opposition socialist leader Alfredo Pérez Rubalcaba accused the PP of hijacking parliament by helping Rajoy to avoid appearing before it to explain himself.
The PP’s former treasurer Luis Barcenas has said in court that the party had been paying illegal money from a slush fund to party leaders, including Rajoy.
The newspaper El Mundo published what it said was the PP’s original ledger with entries showing illegal payments to the PM and other senior party figures.
Rajoy has not been charged and has repeatedly denied the accusations.
