Former police minister Mike Gallacher told Premier Gladys Berejiklian he wanted to attend Monday's party room meeting to witness Mike Baird's resignation speech as he felt he had been treated unfairly by him.

Mr Gallacher has been sitting on the crossbench since being forced to resign as police minister in 2014 over evidence aired at the Independent Commission Against Corruption.

After the ICAC last year tabled its report on Operation Spicer, its investigation into Liberal Party fundraising before the 2011 election, Mr Baird declared Mr Gallacher was not welcome back to the party room or into the cabinet.

The ICAC said it did not consider Mr Gallacher was always a truthful witness and found he had tried to evade political donations laws in accepting money from banned donors, including property developers.
