The sentencing followed an investigation into her misconduct while employed at HMP Preston, which she started working at in 2020.
Her vetting for the role was delayed by the Covid-19 pandemic, by which time Wilkinson, of Preston, had already completed her training and failed to declare any conflicts of interest.
But in April 2021, Wilkinson told her line manager she knew prisoner Gary Hampson and one of his relatives, citing a family connection, the NWROCU said.
She claimed to have submitted a conflict of interest report but records show she only declared a connection to another prisoner and no formal disclosure was made regarding Hampson and his relative.
A month later, reports surfaced alleging a corrupt probation officer was smuggling contraband into HMP Preston.
A subsequent investigation revealed Wilkinson was in a relationship with Hampson, a continuation of a prior relationship and had visited him in prison in January 2018.
She had also been listed as a friend of two other inmates.
A mobile phone seized from Hampson’s cell showed messages between Wilkinson and Hampson, while a card sent online by the officer to the prisoner was also found.
