With all this chat of "people" and "Parliament", it's probably time that we all reviewed the actual motion tabled in the House:
Business Today: Chamber for Thursday 29 August 2013
Note that it is specifically about the use/abuse of chemical weapons and an attempt to push the issue within the UNSC. Any vote on 'British involvement' would have been in the second motion which never happened.
The biggest issue at the time was that the press and opposition were allowed to rebrand this vote into one against military action in Syria; it was never that.
