Greenwich Council's chief executive is following its former leader out the door after announcing she will retire in the autumn.
Mary Ney has run the local authority since 2000. Her forthcoming departure was made public in papers for the council's general purposes committee.
Her announcement comes after long-time council leader and close ally Councillor Chris Roberts quit the local authority ahead of May's elections.
And it means that a job with an annual £185,000 salary is now up for grabs, with the successful candidate chosen by a council appointment panel.
The committee on Friday is set to agree for the job to be advertised, along with the soon to be vacant post of director of adults and older people's services - a job with a £125,000 salary.
A spokesman for Greenwich Council said: "This is old news. The chief executive advised the council in May of her intention to retire sometime this year."
