Telstra CEO Sol Trujillo has resigned and will leave the company at the end of June, according to the Sydney Morning Herald.
Trujillo was brought in to replace Ziggy Switkowski four years ago and launched an ambitious transformation programme, including slashing the number of IT applications in use, to make the incumbent telco more agile and to reduce its cost base.
He engaged in robust battles with both the Howard and the Rudd governments over issues such as regulation around the T3 share offer and the new Labour government's National Broadband Network plan.
Telstra Chairman Donald McGauchie says the company is advanced in its succession planning.
Rumours of Trujillo's departure have been circulating for several months.
