Great news. It's a basic requirement of modern govt and I note that France, Germany, Italy etc have small fleets of A320 series aircraft for govt missions. Only in Britain do people get upset over this.
As for NHT ops, well it's not carrying 200+ passengers and if it can't make it out with an exec load then LHR is literally just down the road. And if it's not actually flown by the RAF then LHR makes more sense.
