Poland's ruling nationalist party aims to stem a decline in its popularity ahead of two key elections this year with warnings that opposition support for LGBT education is a threat to Polish culture and should be blocked wherever possible.

The Law and Justice Party (PiS) has condemned a new school sex education programme planned in Poland's opposition-ruled capital Warsaw, calling it an infringement of traditional Catholic values by Western liberalism. PiS has targeted LGBT rights as it strives to reverse a decline in popularity amid corruption allegations against financial regulators and questions about party chief Jaroslaw Kaczynski's business dealings, among other things.

Poland's European Coalition, an umbrella grouping of opposition parties, has passed PiS by two points ahead of May's European Parliament elections, according to a new opinion poll. Parliamentary elections will follow in the autumn.

The approved lesbian, gay, bisexual and transgender (LGBT) education programme in Warsaw is meant to teach students about sexual orientation, discrimination and reproductive health, according to standards set by the World Health Organization. Conservative politicians, Roman Catholic leaders and commentators argue such lessons will rob parents of the right to decide how their children should be educated and see children discovering their sexuality too early.

"The whole social mechanism of preparing a young person, first a child and then a youth, for future roles as women and men, to start a family, for the role of mother and father, is being questioned. It could be destroyed," Kaczynski told a PiS party convention on Saturday. Read more via Reuters
