Short and sweet, thank you. First minister, you may be aware that the First Minister of Northern Ireland is in favour of abolishing air passenger duty to help air passengers support growth, jobs and cut costs from businesses. Given the Scottish Government has now used its newly devolved power and brought in its Air Departure Tax (Scotland) Bill, as a replacement for air passenger duty, and has committed to reducing it from 2018, what are you going to do to ensure that air passenger duty is devolved, and once it is devolved, what will you do with it?
