Telstra has confirmed the departure of its chief technology officer, Vish Nandlall, amid an allegation the senior executive's resume contained false information.

A Telstra spokesman said Mr Nandlall, who describes himself online as a "telecom visionary", had parted ways with the company after 21 months in his role.

But the spokesman said Telstra would not comment on a report in The Australian on Saturday, which claimed that Mr Nandlall had left the company "under a cloud" after he had "embellished his resume", claiming to have an MBA from Harvard. The Australian also published claims that he had plagiarised presentation material.

"Vish Nandlall has left Telstra after serving as the company's Chief Technology Officer for the past 21 months," the Telstra spokesman said.
