Martin Dalgleish has stepped down from the MediaWorks board, the company has announced.
Mr Dalgleish finished in his role on the June 30. MediaWorks said the decision was because of his "other business interests". The company says he will not be replaced as locally based Jack Matthews recently joined the board, so the number of board directors will remain at five.

Mr Dalgleish said he is confident in the future of the company, "under an excellent management team guided by a first-class board enhanced by the recent addition of Jack Matthews.
"I have every expectation it will continue to thrive and wish it all the best in the future," he said.
