Lib Dem conference: Airport expansion around London
Lib Dems used to be against new runways in the south east of England, but some wanted the party to change its mind and expand Gatwick Airport to the south of the capital.
Daily Politics reporter Eleanor Garnier took the mood box - an unscientific test with a box and plastic balls - to get reaction from delegates in Glasgow on the airport and runway issue.
On Tuesday, Lib Dems voted for the current policy which calls for "no net increase in runways across the UK as a whole", although Nick Clegg had backed the change to allow expansion at Gatwick.
