Around a million people gather at a rally in Warsaw to protest against Poland's conservative government two weeks ahead of a key general election. Called by opposition leader and former premier Donald Tusk, the "Million Hearts March" seeks to mobilise the electorate ahead of the vote. "We are defending our democracy because unfortunately it's under great threat by the authoritarian government that we have in Poland" says Michal, a lawyer who takes part in the demonstration.
