I thank the minister for that reply. As he will know, Prestwick airport, which makes a huge contribution to the economy of Ayrshire and Scotland, forecasts that its annual passenger numbers are set to double over the next 10 years to 5.7 million. A key element identified in the master plan is the need to increase rail capacity on the Ayr to Glasgow line, and in particular the need to increase the current service frequency of two services an hour, especially at peak times. Will the minister support that position? Will he enter into discussions with Prestwick airport, First ScotRail and other relevant agencies to secure that increase in service?
Surface transport to our airports is an important part of the provision that we in Government must make. I shall be supporting Prestwick airport myself when I fly out on Sunday on its direct flight to Poznań for the climate change leaders side event that will take place on Monday and Tuesday. I recognise, both personally and as a minister, the importance of Prestwick airport and its being connected to the rest of Scotland.
