Axel Rudakubana, convicted of the Southport murders, has been charged with three alleged assaults on prison staff and with possessing a weapon at HMP Belmarsh. The allegations raise fresh concerns about safety for prison workers at the high-security jail.

The charges relate to incidents said to have taken place while Rudakubana was in custody at Belmarsh. He has been charged, rather than convicted, so the allegations will need to be tested in court.
