Wasps, who are still not safe from relegation, have returned with their begging bowl to three parties who had previously expressed an interest in the club while issuing an urgent appeal for potential new investors to step forward.

Bath have confirmed that forwards coach and former England lock Martin Haag will join Sir Ian McGeechan in leaving the club at the end of the season.
