Since its accession to power, the national conservative government, appointed by the PiS party (Law and Justice), is systematically altering the state in order to secure its power on a permanent basis. The opposition is having a hard time. The fact that the electoral law should now be adapted to the party’s needs is not really surprising.
The change that hurts the leftist parties the most is the abolishment of the two-round system. This is due to parties having the chance to collaborate before if no absolute majority was achieved. In the new single round system, one can win even with a relative majority.
