Speaking during a campaign rally in the town of Poronin before elections on June 28, Duda asserted that he would continue to pursue pro-family policies.

"These were policies of dignity for Poles and Poland — a dignified fight for Polish interests anywhere, where the truth about those interests had to be spoken. I never feared doing that," he said.

Same-sex marriage, which is opposed by the majority of the population, is banned in the Polish constitution, and Duda emphasized his concern over how the LGBT movement has grown in other countries as a political power grab, not a civil rights cause.

"They are trying to persuade us that LGBT is a category of people, but it's an ideology," he said.

Adding that social benefits to encourage strong families would be maintained, Duda also vowed to defend children from "social experiments," which presumably refers to the sexualization of children at a young age.
