Stobart Group Ltd ( LON:STOB ) has reshuffled its board, as the Southend Airport owner had promised after seeing off a shareholder rebellion at last month's annual general meeting.

Michael Williamson is to join as the interim chief financial officer – although he won't be formally joining the board – taking over from Richard Laycock who chose not to seek re-election last time around. Nick Dilworth, currently the firm's commercial director, has been promoted to chief operating officer, while he will also join the board as an executive director.
