Thousands march in Poland over Acta internet treaty
Prime Minister Donald Tusk says his government will on Thursday sign the Anti-Counterfeiting Trade Agreement.
The treaty, known as Acta, aims to establish international standards to enforce intellectual property rights.
But critics say it could curb freedom of expression, and government websites have been hacked in protest.
Several marches took place in cities across the nation on Wednesday, says the BBC’s Adam Easton in Warsaw.
Crowds of mostly young people held banners with slogans such as “no to censorship” and “a free internet”.
