Queensland premier Annastacia Palaszczuk has stood down minister Mark Bailey after the state’s corruption watchdog found he may have engaged in corrupt conduct.

The Crime and Corruption Commission investigated Mr Bailey’s use of a private email account and found while it was not corrupt, there was “sufficient evidence to raise a reasonable suspicion of corrupt conduct” because he deleted his email account.

The energy and main roads minister allegedly used his personal account to conduct secret negotiations with an Electrical Trades Union official.

Mr Bailey deleted his private email account earlier this year, but reactivated it when media reports alleged he had used it for ministerial business.

“I met with Mark Bailey tonight and I have asked him to stand aside as Minister pending the outcome of the State Archivist investigation into his deactivation of his personal email account,” Ms Palaszczuk said in a statement.

She also said her office has been directed by the commission to develop “further explicit and formal advice to Ministers regarding the requirement that they use their ministerial email address for all ministerial businesses”.
