A number of flights arriving into Birmingham from Spain, Portugal & Ireland arrive from the west (outside CAS) routing BCN-GROVE (previous routing BHD-EXMOR-BCN or STU-BCN). These flights, after leaving CAS are handed over to London Military ATC who route them towards GROVE & then hand them over to Birmingham ATC. B'ham ATC then will probably ask them to route direct GROVE (or sometimes HON) & then vector them towards final app.
