Czech President Petr Pavel has signed into law legislation that treats communist propaganda the same as Nazi propaganda.
The amendment makes the promotion of communist ideology, public display of symbols and calls for support punishable by up to five years in prison.
The law aims to close a legal gap and reinforce historical accountability following the country’s totalitarian past.
Critics warn that wealthy offenders may evade jail through fines.
The move builds on the 1993 Act declaring the Communist regime illegal and reflects wider EU efforts to criminalise totalitarian propaganda.
