Energy Secretary Ed Miliband has said he does not regret voting to block UK military action against then Syrian President Bashar al-Assad in 2013.
Prime Minister at the time David Cameron had wanted to attack Syria, after reports Assad had used deadly chemical weapons on his own citizens in Damascus.
However, Miliband, who was then leading the Labour Party, directed his MPs to vote against the proposal, preventing the UK from taking part in any action.
Speaking on Friday, Miliband defended his decision saying there had been no "clear exit strategy" and he had not wanted to put British troops in "harm's way".
