Looks like LBA have applied to retain some of the DSA CTA and submitted the attached yesterday ahead of the proceedings to close the airspace with the delay to the procedure ending today.
Looks to me to be the Western side of the airspace they want to keep, and they have asked that the base altitude is increased from 4000ft to 4500ft in CTA 8 to not impact GA traffic in the area. As far as I can see there is nothing from Peel as yet to halt the airspace closure, I know Ros Jones submitted a request to hold off for 12 months but expect this has been rebuffed as there is no mention of it on the CAA webpage as of yet.
