As a result of the passing of the resolutions, David Bramhill, Joseph O'Farrell and Dr Zac Phillips have been removed from the Board with immediate effect and Craig Howie and John Americanos have been appointed to the Board with immediate effect.

Craig Howie, incoming Executive Chairman of Union Jack, commented:

"Following the Board changes announced today, Union Jack's immediate priority must be an urgent right-sizing of its central cost base, particularly with regard to directors' remuneration.

"This should be accompanied by significantly improved investor communication and corporate governance.

"Supported by a fresh commercial and technical approach, the incoming Board also needs to make considerably more effective capital allocation decisions at the asset and corporate levels, to preserve and grow value going forward.

"We look forward to updating shareholders once the most urgent steps have been taken, including the selection and appointment of independent non-executive directors to ensure the highest standards of boardroom oversight."
