Two prison workers at the jail where Conrad Black spent more than two years say he wasn't the model inmate his defence team paints him to be in a filing to be heard at his resentencing later this month.

In an affidavit filed in a U.S. court, a unit manager at Coleman prison in Florida says the former media baron demanded special treatment and gathered an entourage of inmates who acted like servants for him.

The document claims those inmates cooked and cleaned for him.

In another document, an education specialist who supervised Black as a tutor says he was frequently late and often read or worked on writing what appeared to be a book while he was supposed to be teaching.

The specialist claims Black projected an air of superiority and some of the inmates saluted him each day in class.

Black's defence has filed documents in advance of a June 24 resentencing on his two remaining convictions that tout his "extraordinary" contributions to the community during 2 1/2 years at Coleman.
