A set with a ‘a very good reputation in the sports field‘, 4 New Square is active in sports discipline and anti-doping matters. 2019 silk appointment Daniel Saoul QC represented then-Toronto Wolfpack rugby league player Ryan Bailey, who was found to not be at fault for refusing a post-match drug test; the player suspected that bottles of water provided by the Canadian anti-doping authorities may have been interfered with. Kendrah Potts acted as sole counsel defending England cricketer Alex Hales in ECB disciplinary proceedings after his highly publicised involvement in a brawl after he and team-mate Ben Stokes intervened in a homophobic attack; Stokes was acquitted of affray in a criminal case arising from the same incident. Notably, a number of the set’s members have experience of elite sport themselves –Saoul QC is a former elite rowing cox, Graeme McPherson QC has had success as a race horse trainer, and Diarmuid Laffan is a former U21 Ireland rugby union international loose forward.
