Jag Sanger, the former managing director of The Market Herald, has accused the major shareholders of the ASX-listed operator of Gumtree, HotCopper and the eponymous financial publication of “shameful” behaviour, denigrating his ousters as a “mid-level accountant” and a “yoga teacher” who have “tanked” the firm.

Mr Sanger, who has not before spoken publicly about his ouster from The Market Herald, was dumped from the Perth-headquartered publisher late last year in a boardroom coup orchestrated by David and Gavin Argyle, the father-son major shareholders of the company. Shares in The Market Herald have dropped more than 30 per cent this year, and last traded at 30¢.
