On 10 April 2010, a Polish Air Force plane on route to Smolensk crashed killing the Polish President Lech Kaczyński and 95 others, many members of the Polish elite. In the aftermath Janusz Palikot founded a new political party, Ruch Palikota, initially named after himself. The party was anti-clerical, pro-pot, pro-EU, pro-gay marriage and in favour of flat taxes. It attracted mainly entrepreneurs as candidates, one of whom was Anna Grodzka, and another was the openly gay Robert Biedroń. In the October 2011 elections the new party received 10% of the vote and 40 seats in the Sejm. Grodzka and Biedroń became list MPs. In 2013 Grodzka was nominated for Deputy Speaker, but the MPs voted to keep the incumbent.
