A Sheppey prison officer has resigned amid allegations she had an inappropriate relationship with a murderer.

A national newspaper says Shirley Fowle fell for Alan Dalby while he was serving his life sentence for strangling his former girlfriend.

They met at Swaleside prison on the Isle of Sheppey.

A Prison Service spokesman said: "A prison officer resigned last week from HMP Swaleside following allegations of an inappropriate relationship with a prisoner.

"The vast majority of our staff are honest and hard-working, but one officer can jeopardise the safety of the whole prison. Swaleside prison supports a culture which values integrity above all."
