The party, of which Racan was a long-time leader, said that a book of condolence would be opened at SDP headquarters on Iblerov Trg square as of 1300 hrs today.
Books of condolence will also be opened at SDP branch offices throughout Croatia.
The party reports that the 63-year-old Racan, who died of cancer early Sunday morning, will be buried at a private ceremony for immediate family and close friends only, according to his wish.
That is why there will be no official announcement of the date and place of the funeral of the former Croatian Prime Minister.
