Senior members of France's ruling party rebuffed opposition calls for a parliamentary vote on whether to take military action against Syria, saying on Monday thatlawmakers should respect the president's constitutional right to decide on attacks.
President Francois Hollande's demands for Syrian President Bashar al-Assad to be punished for an alleged chemical strike have left him out on a limb since Britain's parliament voted against taking part in any action and U.S. President Barack Obama said he would seek Congress's approval before any assault.
Hollande is the army's commander in chief under the French constitution and empowered to order an intervention. His sole obligation is to inform parliament within three days of action starting.
Only if it were to last more than four months would he be obliged to seek parliamentary approval for it to continue.
With opinion polls showing up to two-thirds of the public would oppose intervention in Syria, several conservative, centrist and green politicians called over the weekend for France to hold a special parliamentary vote.
Health and social affairs Minister Marisol Touraine told Reuters there was no reason to do that. "There is a framework and we must respect it," she said. "The issue is too serious to be opened up to political posturing."
"In a complicated situation like this, we need to stick to principles, in other words the constitution, which does not oblige the president to hold a vote, nor even a debate," foreign affairs committee chief Elisabeth Guigou, a veteran of the ruling Socialist Party, told France Info radio.
"I don't see that holding a vote would make any sense politically," she said, noting France would be left in an impossible situation if parliament voted in favor of action and then the U.S. Congress voted against.
Interior Minister Manuel Valls also said over the weekend that the constitution should be respected.
But Alain Juppe, foreign minister under conservative former president Nicolas Sarkozy, said a vote was needed because the U.N. Security Council had not backed any attack on Syria.
"We're in a specific context here. ... It would justify a vote in parliament," he said.
PM to unveil intelligence
Parliament is due to debate the Syria crisis on Wednesday.
The last time parliament voted on military action was in 1991 when then-Socialist president Francois Mitterrand sought its support for his decision to join the U.S.-led coalition in the Gulf War.
Guigou said doing nothing would signal to all authoritarian rulers that using chemical weapons against civilians can go unpunished. She acknowledged France would not act on its own.
"To give an intervention legality it would need to be carried out by a broad coalition," she said.
Prime Minister Jean-Marc Ayrault told reporters he would show parliament leaders evidence in a meeting on Monday proving that Assad's forces used chemical weapons in anAug. 21attack thatWashington says killed more than 1,400 people.
A declassified French intelligence document published by the weekly Le Journal du Dimanche and confirmed as authentic by a government official said Syria's chemical weapons arsenal included sarin, VX nerve agent and mustard gas.
Syria had about 1,000 metric tons of chemical weapons, one of the world's largest such arsenals, it said. The agents could be delivered with long-range missiles, aerial bombardments or short-range artillery, it added.
A BVA opinion poll released on Saturday showed 64 percent of respondents opposed taking military action in Syria, 58 percent did not trust Hollande to conduct an operation, and 35 percent feared that strikes could set the Middle East "ablaze."
