Sunday is the second and last day of voting in Serbia in a referendum on a new constitution which would declare Kosovo an integral part of the country. Members of small opposition parties are urging Serbs to boycott the vote. They say the constitution is a backroom deal among the major parties. Though Kosovo’s status is central to the constitution, the province’s two million Albanians have not been invited to vote and have ignored the poll. They say it will have no impact on their demand for independence.
