Baby killer Constance Marten has been told to befriend Lucy Letby 'for protection' as she faces life behind bars inside a notorious prison dubbed the 'female monster mansion'.

The socialite is locked up at Surrey's HMP Bronzefield where she previously whinged in a prison magazine about her treatment.

The runaway aristocrat, 38, had already reportedly become close to Sara Sharif's killer stepmother Beinash Batool during her murder trial.

Batool has already struck up a friendship with killer nurse Letby where the pair play Uno together and make cheese toasties together in the kitchen.

Violence is said to be rife on the ward with child killers a target among other inmates.
