Ardent Leisure chief executive Simon Kelly said the flooding and closure of five retail outlets in Houston by tropical storm Harvey would do nothing to alter the company's strategy of clustering centres in locations such as Texas.

As it reported audited figures for the year to June showing a net loss of $64.5 million, the challenged entertainment company said on Thursday the tropical storm that has killed at least 31 people had forced closed five leisure centres in Houston – out of a total 37 in its Main Event Entertainment division – and that it was assessing a further three for possible damage.
