Krupa remained in parliament until his defeat in the 2011 parliamentary election. He was elected as the Marshal of Lesser Poland on 5 November 2015, becoming the fifth head of the regional government for the province. However, the opposition Law and Justice party challenged Krupa"s appointment as marshal as illegal, arguing that the previous marshal, Marek Sowa, along with his board, had yet to submit their resignations before Krupa"s appointment.
However, the claim was rejected by the marshal"s office.
