Kovacevic, who presented his platform at a news conference in Zagreb, said that he was financing his campaign with money from the sale of his books and his friends' donations.
Kovacevic said that if he was elected president, he would defend national interests rather than conduct "the policy of servility". He also announced plans for the spiritual revival of the country.
If he wins the elections, Kovacevic will open a separate office for relations with Bosnia-Herzegovina and the Croat people in that country.
