A Polish diplomat charged with improving contacts with Jews worldwide has been fired after he criticised his own government's approach to regulating Holocaust speech, the foreign ministry said.

Jaroslaw Nowak, the plenipotentiary for contacts with the Jewish diaspora described a Holocaust speech law passed by his country's ruling party as "stupid".

Mr Nowak also said Poland should pass a law on property restitution, a statement implying further criticism of the ruling authorities, who recently passed a law cutting off the chances for restitution or compensation for those who had properties seized by the communists.

Among those affected are Holocaust survivors and their heirs.

Foreign minister Zbigniew Rau fired Mr Nowak on Saturday, the ministry spokesman, Lukasz Jasina, announced on Twitter.

The development comes only days after Poland recalled its new ambassador to Prague after that diplomat criticised his own country, in that case, in relation to Poland's approach to a dispute with the Czech Republic over a state-run coal mine.

The dismissal of Mr Nowak came a day after an interview was published by Jewish News UK in which Mr Nowak said legislation passed in 2018 seeking to ban certain statements about Poland and the Holocaust "is one of the stupidest amendments that was ever done by any law".

The legislation sought to fight back against false claims that Poland, a victim of Nazi Germany, bore responsibility for the Holocaust.

It outraged Israel, where many felt it was an attempt to whitewash the fact that some Poles did kill Jews during the German occupation during the Second World War.

The legislation originally outlawed blaming Poland as a nation for Holocaust crimes committed by Nazi Germany, with prison terms of up to three years for falsely attributing German crimes to Poland.

It was later amended to remove the criminal provisions.

Last year Poland also approved a law that sharply restricts the rights of Holocaust survivors or their descendants to reclaim property seized by the country's former communist regime.

That law provoked a serious diplomatic dispute with Israel which still remains unresolved.

"I think at some point Poland will have to really come to the conclusion that we have to do something about" restitution, Mr Nowak said.

Mr Nowak has been involved in Polish-Jewish dialogue since the 1980s.

He became the plenipotentiary for contacts with the Jewish diaspora in July.
