Health Service Medical Supplies (Costs) Bill

The early part of the Bill appears incredibly tortuous, because it relates to whether something is under the voluntary scheme or the statutory scheme and to switching back and forth between the two. Is that because we have a voluntary scheme which started in 2014 and will run until 2019, and the Government intend not to renew it? If the Government are minded to consider renewal in 2019, why have parallel schemes making the whole thing much more complex than it needed to be?
