Rainbow Rose has many objectives including, but not limited to: Creating a strong LGBTI Social Democratic network in each EU Member State; promoting LGBTI issues within the PES family; supporting LGBTI initiatives in the different Council of Europe member states; and cooperating with LGBTI organisations to realise equality for all LGBTI European citizens.
