The campaign, which lasts until May 12, was presented in Zagreb by party official Robert Prugovecki, who said its purpose "is for citizens to take part in direct democracy and put questions through our MPs to ministers who have the duty to respond within 30 days."
He said the party would ask the government to provide constructive answers to constructive questions. "We are interested in what citizens think and feel at present and what their attitude is to the government."
He said the party decided to launch the campaign ahead of the May 1 International Workers' Day because "labour is in danger."
"Jobs are disappearing... It's evident that the government isn't willing to carry out structural reforms and that it's willing to make citizens even poorer," said Prugovecki.
