We have sent an important message today: that anyone using chemical weapons must be identified and held to account.

Today, the States Parties to the Chemical Weapons Convention agreed by a large majority to allow the Organisation for the Prohibition of Chemical Weapons (OPCW) to identify those responsible for attacks involving chemical weapons. I am pleased that so many states have joined us in supporting the proposal. Today we have strengthened the Chemical Weapons Convention and the OPCW. It was not an easy process, but the outcome shows that fighting to uphold international regulations is worthwhile.
