The UK must wait to receive details of Syria's chemical weapons stockpiles that have been received by an international watchdog.
The Organisation for the Prohibition of Chemical Weapons (OPCW) confirmed it had received the "expected disclosure" from the Syrians and was "currently reviewing the information".
The Foreign Office, though, said the "unique case" of Syria has forced a delay:
It has made this disclosure as a non-state party. The coming OPCW executive council needs to endorse a new process to handle Syria's chemical weapons.
Once this has been achieved, the OPCW will be in a position to make the Syrian disclosure available to states' parties.
In consultation with partners we will reach a judgment on its credibility. This is only the start of a long and complex process.
