SUE GRAY, the senior civil servant who busted Boris Johnson over Partygate, has resigned to work for Labour.
The top mandarin is set to be named as Sir Keir Starmer’s new Chief of Staff.
Sue Gray has resigned from the civil service to join the Labour Party
She’s understood to have resigned from the Cabinet Office this afternoon.
But she’ll have to wait at least three months before she can start working for Sir Keir, as per the Civil Service code.
Ms Gray will also have to get the nod from Rishi Sunak, who has the final say over career moves out of Whitehall.
The civil servant shot to fame in 2021 when she took over the No10 partygate probe from Simon Case.
She spent months reading hundreds of witness accounts and interviewing scores of Downing Street staff about illegal boozing at the heart of government.
In her final report, Ms Gray tore into Boris Johnson, describing “failures of leadership and judgment” inside No10.
The mandarin said “too little thought” was often given to the public’s hardship during the pandemic.
And she blasted the booze culture inside government, demanding changes in behaviour be made.
