DNA, Finland’s third-largest mobile operator, has announced that CEO Riitta Tiuraniemi (pictured) is resigning, as the company starts the search for a replacement who has “a vision of where DNA’s new opportunities lie.”

The board said it had reached agreement with Tiuraniemi that she would resign. Jukka Leinonen, vice president, corporate business, has been appointed Acting CEO, while a replacement is sought.

The aim is to appoint a new CEO by the end of this year.

In a statement, interim CEO Leino said: “The telecommunications industry is undergoing a major disruption. The new CEO will need to have a very dynamic approach and a vision of where DNA’s new opportunities lie.”

Tiuraniemi’s departure comes after DNA’s owners dropped plans to sell the operator in July, citing market conditions.

The company has also just announced that its proposed acquisition of pay-TV operator PlusTV has been approved by the Finnish Competition and Consumer Authority. The acquisition was announced at the end of April.
