Betsi Cadwaladr NHS changes: Prof Jonathan Montgomery's views

Campaigners opposing a raft of changes to hospital care in north Wales have demonstrated in Llandudno.
It follows a decision by the area community health council (CHC) not to refer Betsi Cadwaladr University Health Board (BCUHB) plans to the Welsh government.
Serious neonatal baby care will move to England, and a number of community hospitals will close.
The health board says it has made hard decisions but has a responsibility to provide safe and sustainable care.
Jonathan Montgomery, professor of healthcare law at Southampton Law School, explained the role of CHCs to Peter Johnson on Good Morning Wales.
