"The new constitution is expected to be ratified and the constitutional law adopted next week, and parliamentary elections could be called the same day," Dinkic told a press conference called by his party, a junior partner in Serbia's ruling coalition.
Dinkic, who has tendered his resignation to the post of finance minister, said parliamentary elections must be held next month, while President Boris Tadic and Prime Minister Vojislav Kostunica should agree about the presidential election.
Speaker Predrag Markovic said parliament was expected to proclaim the new constitution on November 5.
Whether the law on its implementation will be passed the same day depends on consultations parliamentary parties are due to hold this week. This law is also expected to settle the issue of parliamentary elections. The date of parliamentary and presidential elections is currently the main stumbling block on the Serbian political scene.
Tadic's Democratic Party advocates holding both ballots by the end of the year, while the Socialists and the Radicals feel parliamentary elections should be held and the new government formed before the presidential election. They advocate holding parliamentary elections next spring. Kostunica's Democratic Party of Serbia has not taken a position yet.
