Elmer Funke Kupper, the former boss of the Australia Securities Exchange (ASX), is stepping down from his post as one the directors of Australia’s biggest sportsbook Tabcorp Holdings Ltd.

The Australian reported that Kupper, who has been on a leave of absence since authorities launched an inquiry into his supposed anomalous business dealings in 2016, will be leaving the company in October. Tabcorp has yet to announce Kupper’s replacement.

Kupper has been a known fixture in Tabcorp for more than a decade. He was appointed as Tabcorp’s Chief Executive for Australian Business in February 2006, and then assumed the role as Tabcorp’s Managing Director and Chief Executive Officer in September 2007.

In June 2011, Kupper stepped down from his post in Tabcorp to take up the leadership of the Australian Securities Exchange (ASX). Tabcorp named incumbent CEO David Attenborough as his replacement at that time.
