Belgium ? Poland and Britain threatened Thursday to exercise their vetoes to prevent plans to draft a watered-down EU treaty at a European Union summit, with Warsaw demanding more voting rights and London refusing to cede some powers to Brussels.

British Prime Minister Tony Blair said he would reject any treaty that is similar to the draft constitution French and Dutch voters rejected two years ago.

In Warsaw, Polish Prime Minister Jaroslaw Kaczynski said the plan proposed by German Chancellor Angela Merkel, the summit host, remains a problem.

The EU is considering a voting system that takes into account each country’s population.

But Kaczynski has said Poland wants compensation for the deaths it suffered during World War II, when Nazi Germany invaded. He argues that his country would have more residents now if not for the war.
