Poland's President Andrzej Duda has pardoned a minister in the country's new conservative government who had been convicted of abuse of power.

Duda pardoned Mariusz Kaminski, the coordinator of special services in the new government of Prime Minister Beata Szydlo, responsible for overseeing police and intelligence agencies.

The pardon was announced late Tuesday. It comes as one example of the strong cooperation between Law and Justice, the country's ruling right-wing party, and Duda, who won the presidency on the party's ticket.

Kaminski was the head of the Central Anti-Corruption Bureau when Law and Justice last ran the government, from 2005-2007. Earlier this year he was sentenced to three years in prison for abusing his power in 2007 as head of the anti-corruption body. He had appealed the ruling.
