Suzanne Wylie, who currently heads up Belfast City Council, is due to move to the Island next month.
Her predecessor, Paul Martin – who carried out the role on a temporary basis following the resignation of Charlie Parker – is due to move to London to take on the role of interim chief executive at the Borough of Ealing.
He is due to leave the Island in February but will remain available to the government throughout the month. He will not be receiving any ‘exit or termination payment’, according to the government.
In a statement, Mr Martin said: ‘I have loved my time in Jersey and would like to thank everyone I have worked with for the opportunity to serve the Island as interim chief executive. I’ve made many new friends and colleagues with whom I will keep in touch in the months and years ahead.
‘I’m pleased to now have the opportunity to help Ealing council over the coming months and aim to move the council forward in partnership with elected members.’
