The boss of the firm formerly known as Stobart Group has resigned from his post and is set to take on a new role as chief executive of global aviation services business Swissport.
Warwick Brady has stepped down from his role at aviation and energy infrastructure group Esken Ltd.
In an announcement to the markets on Tuesday, the firm said Mr Brady will remain as chief executive until the end of June at the latest - allowing sufficient time to ensure "continuity and a smooth transition".
He will not be entitled to any payments other than his contractual entitlements for the period up to his leaving date.
David Shearer will take on the role of executive chairman on an interim basis.
Executive Chairman David Shearer said: "I would like to thank Warwick for all of his efforts during his time as Chief Executive. He has led the transformation of Esken into an operationally focused business and was instrumental in establishing London Southend Airport as a key London Airport asset.
"In the last 12 months, he has dealt with the challenges which the business has experienced due to the Covid-19 pandemic. The board wishes him well in his new role.
"All of Esken's businesses benefit from strong experienced operational management teams with the capabilities required to take the business forward. I look forward to working with Lewis Girdwood, Nick Dilworth and all of our people and stakeholders as we navigate the recovery into the post COVID period."
The announcement said Mr Shearer's initial priority will be to review Esken's strategic options as the company navigates the continuing impact of the pandemic.
As part of that exercise he will determine the leadership requirements for a new CEO.
Chief executive Warwick Brady added: "It has been a privilege to lead this business over the past four years. I am grateful for the support of my highly dedicated and professional colleagues. Esken is a strong company with great people and I wish David and the team every success."
