Demonstrators hold Polish national flags during an opposition rally in Warsaw on September 29, 2012. Mustered by organisations including the Solidarity trade union, the ultra-Catholic media broadcaster-cum-political movement Radio Maryja and the main conservative opposition party Law and Justice, the demonstrators flooded in from across Poland. They are united in their antipathy towards centrist Prime Minister Donald Tusk, with a range of concerns meshing together. AFP PHOTO/JANEK SKARZYNSKI
