The headline in the Belfast Telegraph reads :

‘Belfast psychiatrist Miller to face cash dealings probe behind closed doors’

however this is somewhat misleading, as on talking with the British Medical Council (BMC) I was informed by Mr Jason Day of the Press Office, that Dr Miller was currently under ongoing investigations, but that Interim Orders Panel IOP) had placed some restrictions on him, which can be seen on their website.
It is the case that IOP do hold their deliberations in camera, but this is normal and not just because of this case.
Dr Miller has reached the headlines because of his links with  ex-Democratic Unionist Party (DUP) MP Iris Robinson; he acted as a former health adviser and is believed to hold controversal views on being able to cure gays!
 
The case is ongoing
