Stockholm  - Swedish Prime Minister Fredrik Reinfeldt said Wednesday he believed Czech President Vaclav Klaus will ratify the Lisbon Treaty, but could not say when it will take place.

"We have agreed to get this (the treaty) in place," Reinfeldt told Swedish radio news. The Lisbon Treaty is aimed at streamlining decision making in the European Union.

The Swedish prime minister, whose country is the current holder of the rotating EU presidency, said he has had new talks with Klaus and Czech Prime Minister Jan Fischer.

"I feel confident after the discussions I have had that there will be a ratification from the Czech side, " Reinfeldt said.

He could not give a timetable since the Czech Constitutional Court was to hear a legal challenge against the treaty.

Klaus has called for an opt-out from the Charter of Fundamental Rights, a part of the European Union's reform treaty, before he ratifies the pact.

The Czech opt-out was likely to be discussed when EU leaders are set to meet for their regular summit in Brussels next week.

Concerns raised by Klaus were that the rights charter puts property rights of the Czech citizens at risk as it would allow so- called Sudeten Germans, who were expelled by then Czechoslovakia after World War II ended in 1945, to sue for their confiscated property.(dpa)
