A specific question on waiting times during the bad weather that we've just experienced—we are aware of the particular pressures put on the ambulance service because of the snow. I've heard one particularly concerning report about the impact of waiting a very long time on a specific patient. Heavy snow isn't something that happens on a weekly basis, but neither is it something that's entirely exceptional. Can the First Minister refer us to information that will provide us with assurances that the ambulance service does plan as much as possible in order to cope when we do experience circumstances of extreme weather as we had last week?
