According to RMF radio, PiS are set to scrap the direct election of city presidents and return to the old system whereby the city council votes for the president.
Under the present system, residents of Wrocław on the electoral register are able to vote for their prefered presidential candidate in a seperate ballot.
However, speculation is rife that PiS will return to the system that was used 15 years ago. Given that PiS' Adam Lipiński has told Gazeta Wrocławska that the government are "considering such a project", the rumours do appear to have some substance too.
If the changes become law, current Wrocław President Rafał Dutkiewicz would be the city's last directly elected president.
Despite enjoying huge levels of support in the opinion polls (in some cases over 40%), PiS are still not as popular as they would like in the big cities. Some observers see Poland's big cities as the last bastion of the opposition parties, something that the Polish Government are obviously keen to change.
Critics of the move claim that PiS are making the changes due to fears the party dont have strong enough local candidates and personalities to win presidential ballots in big cities. When it comes to general popularity PiS enjoy much more support. Therefore they would stand a better chance of winning the councils, which would then allow them to vote in their prefered city presidents.
On the other hand, supporters of the change believe that city presidents would be kept honest by the threat of the council using the vote of no confidence to remove them from power.
