In the biggest management reshuffle at Microsoft since Satya Nadella took over as its chief executive, two top executives, Tony Bates and Tami Reller, will leave the company while a former Clinton family aide will become its chief strategy officer, according to media reports.

Mark Penn, who will become chief strategy officer, will get a bigger hand in determining which markets Microsoft should be in and where it should be making further investments, the New York Times reported, citing a person briefed on the change.

Penn was an executive vice president at Microsoft overseeing advertising and strategy.

Bates, the former Skype chief executive in charge of Microsoft’s business development, will leave immediately, technology news site Re/code reported on Sunday citing unnamed sources. – ( Reuters )
