In Wales, the Assembly may have devolved powers over it in the future, which would aid the Welsh aviation sector. In England unless people appeal i think its there to stay !
How can it be here to stay if it's not even here yet?
Devolving apd powers is one option being considered by the UK Treasury.
It may well not happen but the Bristol Airport management has pointed out how uneven apd rates across the UK could distort the market.
