Legendary Swedish pop group, Abba, have come together for the first time in ten years to sign souvenirs in support of gay rights in Poland.

Agnetha Fältskog, Björn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad are offering signed posters, photos and music on auction site eBay to raise money for Warsaw Pride in Poland, which has come under attack by president Lech Kaczynski.

The memorabilia is being auctioned by the organisers of Stockholm Pride, “As arranger of a Pride festival in a neighbouring country that is so privileged by comparison it is impossible to be aware of what is happening in Poland without doing something,” said Stockholm Pride chairwoman Ulrika Westerlund.

Mr Kaczynski banned last summer’s gay pride celebrations in Warsaw after saying that homosexuals were “not a natural part of Poland’s culture,” and told gay people to repress their sexuality.

Abba are the most well known celebrities to have made donations to the auction so far.
