Indeed - but beyond that first 100 - which other ones?
Im not sure you’d see an announcement soon on that. As I read it’s simply a “consultation” for now, and they’ve given themselves the best part of 10 years to action it. The talking and planning could take some years.
However given their lease deadline, they may decide to accelerate the process of this first 100 (depending on the complexities involved). The majority or indeed all of the 4600 may well be done earlier than the deadline they’ve announced for the first 100, based on the intimation is that closure of the 98% remainder *could* be accelerated. Still its a massive programme of work - close to 500 exchanges per year if they really want out by 2031.
