RBG Holdings, the professional services group behind law firm Rosenblatt, has reported a £4 million cash write off to the London Stock Exchange after losses incurred by its litigation finance subsidiary.

In a trading update from earlier this week, the group said that the subsidiary, 'LionFish', had "recently lost two of the cases that it has invested in", and that following a review, RBG's board had concluded that any further appeals on these cases were no longer viable.
