Luminar, the nightclub operator, has warned of further deterioration in trading, just weeks after it said it faced a “significant risk” of not meeting full-year market expectations.

For the 7 weeks to October 15, like-for-like sales at Luminar’s 88 late night venues were down 14 per cent – a sharp acceleration on the 9 per cent decline it reported for the first three weeks of September and the 4.5 per cent decline it reported for the six months to August 27.
