Istanbul (CNN) -- A leader of Turkey's ruling party held out the possibility of a vote on what to do with the Istanbul park where planned razing triggered two weeks of anti-government protests but said demonstrators must leave the park. "The Turkish government will not accept Gezi Park protests to be continued forever," Huseyin Celik, deputy chairman of Prime Minister Recep Tayyip Erdogan's AK Party, said after meetings with a delegation of "popular artists" involved with the demonstrations. His comments were carried by the semi-official Anadolou News Agency. Celik said the government could hold a referendum on the redevelopment of the park, the last green space in central Istanbul -- but he urged the demonstrators to "walk out."
