Leslie Perrin is the chairman of Calunius Capital LLP, an office he has held since January 2009.

Since its establishment in November 2011, Leslie has also been the chairman of the Association of Litigation Funders of England and Wales, and in that capacity is deeply involved in the development of litigation funding as an international phenomenon. At around the time of this appointment, Leslie was named by The Times as one of ‘those lawyers we believe to be the most influential in society right now’.

Leslie has more than 30 years’ experience of litigation markets, having been successively head of litigation, managing partner and senior partner at international law firm Osborne Clarke. One of his cases still holds the record for a UK jury award of defamation damages against an insured defendant. In other cases, he became recognised as one of the pioneers of group actions in the UK.

For nine years until 2015, Leslie was also the senior independent director of DAS, the UK market leader in legal expenses insurance.
