The 52-year-old denies the attempted murder charge, wounding Alison Smith with intent to do her grievous bodily harm and unauthorised possession in prison of a knife or offensive weapon (a pronged metal bar). The charges relate to an incident at the prison in South Littleton, Evesham, on October 10, 2017.
