 In 2006 Wałęsa quit Solidarity in protest of the union's support of the ruling right-wing Law and Justice party, and Lech and Jarosław Kaczyński — twin brothers who had been prominent in Solidarity and were now serving as the country ’ s president and prime minister, respectively. The main point of disagreement was the Kaczyńskis ’ focus on rooting out those who had been involved in communist rule and their party's attempt to make public all the files of the former communist secret police. Until then only members of the government and parliament had to declare any connection with the former security services. Wałęsa and his supporters argued the so-called transparency legislation advocated by the government might turn into a witch hunt and the more than 500,000 Poles who had possibly collaborated with the communist secret police could face exposure.
