MADRID (Reuters) - Spanish and European champions Barcelona will disclose the details of their collaborative agreement with the UNICEF at a ceremony at the United Nations headquarters in New York on Thursday.

Barca said on Wednesday that club president Joan Laporta would attend the event where he would give details of the ground-breaking initiative.

The club announced last May that they had agreed to donate 0.7 percent of annual income starting from the 2006/07 season to the United Nations as a contribution to the organisation's Millennium Development Goals campaign.

Barca, whose motto in Catalan is "mes que un club" (more than just a club) predict that this season's income will be in the region of 240 million euros (163 million pounds).

The UN's Millennium campaign aims to reduce extreme poverty, hunger and infant mortality, achieving universal primary education and promoting sexual equality.

The agreement will also mean the team's famous scarlet and blue shirts carry the UNICEF emblem.

Barca are one of the few leading European football teams not to carry commercial sponsorship on their shirts.
