WARSAW, Poland, July 10 (UPI) -- Jaroslaw Kaczynski, the twin brother of President Lech Kaczynski, has been appointed Poland's new prime minister, Polonia Radio said Monday.
Jaroslaw Kaczynski replaced Kazimierz Marcinkiewicz, who had led the Polish government since the fall.
Lech Kaczynski accepted Marcinkiewicz's resignation Friday amid political tensions in their conservative Law and Justice party.
The twin brothers Kaczynski have been involved in disagreements with Poland's neighbors, Germany, France and Russia and European Union's partners.
The leadership of the ruling Law and Justice party has nominated Marcinkiewicz, considered one of Poland's most popular politicians, as its candidate for the mayor of Warsaw in upcoming local elections.
