Luxembourg goes to the polls on Sunday in the last referendum on the draft of EU constitution of 2005.
   Luxembourg’s Prime Minster Jean Claude Juncker vows to resign if the country .says "no" to the treaty, which is aimed at streamlining decision making in Europe after the trading bloc enlarged from 15 to 25 member states.
   French and Dutch voters have already sent a resounding "no" to European leaders that they do not want the 448-article treaty.
   Opinion polls taken in July last month indicate that the poll could go either way. Opinion polls are banned during the month prior to the election.
   Luxembourg’s parliament ratified the treaty in its first reading on June 28th, but a second reading will be axed if the voters say no.
