If I may presume to say so, I think that Meldex may be asking whether there has been any "general" pre-notam indication that GPS jamming will take place. I have not personally heard of any statements of that nature, and the effects of it anywhere near the restricted or prohibited zones would, I would have thought, led to infringement armageddon and carnage and aircraft wreckage all over the streets of London.
