Where do parties stand on Syria?

Last week, the United Nations Security Council unanimously passed a resolution, drafted by the French, to "redouble" action against Islamic State (IS) in the wake of the Paris attacks. Throughout the history of the UN Security Council, there have been many incidences upon which the members have failed to reach unanimous agreement (for example, in July 2015 when Russia vetoed a resolution in relation to its action in Ukraine, or in May 2014 when both China and Russia vetoed a resolution condemning the state of Syria). As a member of the UN Security Council, Britain has therefore agreed to step up efforts against IS - but because of the convention of parliamentary sovereignty in the UK, this needs to get through parliament before David Cameron commits Britain to any military intervention.
