The first sentence of the article is "Under the current rules prisoners are prevented from receiving parcels unless they have 'exceptional circumstances', such as a medical condition."

Yes, I saw that, and I thought it was incorrect. After some digging:

This does not apply to remand prisoners.

Convicted prisoners get 1 parcel of clothing after conviction (at the governer's discretion).

Also exceptional circumstances "could include for example ... replace clothing due to restricted access to laundry facilities."
