Poland's ruling party leader Jaroslaw Kaczynski has again demanded that Germany pay Poland damages for World War II.
"This is a Polish-Germany issue, I mean it was Germany who invaded Poland, murdering millions of people, destroying material goods and we must be compensated for this," Kaczynski said in an interview with public radio on Thursday.
His party wants €780 million (NZ$1.3 billion).
"For many, many years, there has been a defamation campaign offending Poles, completely altering the sense of World War II," Mr Kaczynski said.
"Today we have started on a route in the opposite direction and I think this road will be difficult and steep... If we did nothing, we would get nothing."

Poland is yet to file an official claim for damages, not wanting to hamper cooperation within the EU and its relationship with present-day Germany.
Mr Kaczynski also said Polish-US relations suffered due to Polish legislation that threatened jail terms for people who suggest the Polish nation was complicit in Nazi crimes against the Jews.
The legislation was watered down this week after months of negotiations with Israel.
