Richard Brook, a non executive director of the UK's largest nightclub chain Luminar, is stepping down from the board. A statement from the group, which is led by Stephen Thomas, said: “ After four years of service as a non executive director, Richard Brooke has today stepped down from the board. “Richard is increasingly focused on his other business interests, in particular the development of Setanta Sports Holdings Limited where he is an executive director.” The news comes just weeks after Luminar announced a 1.6% increase in like-for-like sales for the financial year before February 28.
