Cameron set out his case for military intervention to Parliament in November.[133] Corbyn's Shadow Cabinet met after the Prime Minister's statement in which Corbyn said he would continue with efforts "to reach a common view" on Syria, while Shadow Foreign Secretary Hilary Benn suggested the case for air strikes was "compelling".[134] Corbyn sent a letter to Labour MPs saying that he could not support military action against Islamic State: "The issue [is] whether what the Prime Minister is proposing strengthens, or undermines, our national security...I do not believe the current proposal for air strikes in Syria will protect our security and therefore cannot support it."[133] Amid widespread reports of division in the Parliamentary Labour Party, Corbyn insisted that the final decision on whether the Labour Party would oppose air strikes rested with him.[135] Corbyn eventually agreed that Labour MPs would be given a free vote on air strikes when the issue was voted on. 66 Labour MPs voted for the Syrian air strikes, including Hilary Benn and Deputy Labour Leader Tom Watson, while Corbyn and the majority of Labour MPs voted against.[136][137][138]
