The accounts show the firm, founded by Nigel Eccles, Lesley Eccles, Tom Griffiths, Rob Jones and Chris Stafford in 2009, made an operating loss of $75.7m.

The company said losses continued to be made in 2017 because of lower than expected revenue, costs linked to its scrapped merger with US rival firm DraftKings, and continued investment in products and customer acquisition and retention.
