Ladbrokes and Coral owner Entain has launched a review of all its brands, raising the possibility that some of the biggest names in betting could be put up for sale, after a “difficult year”.

Entain swung to a huge £878 million [$1.12 billion] loss, mostly due to one-off items. The biggest of those was its settlement of a long-running bribery case related to a since-closed Turkish subsidiary and executives that are no longer with the firm. Underlying profits were stronger, rising to £1 billion, but were held back by new safer gambling rules in the UK, which Entain implemented before many rivals.

Finance boss Rob Wood told the Standard that the firm sees an opportunity to pick up customers once smaller rivals are forced to implement the same reforms, though this was likely to mean higher marketing spend in the short-term.
