Departing Microsoft boss Steve Ballmer has hosted his last company meeting - bidding a tearful farewell to employees he has worked with for 33 years.

The 57-year-old danced to Michael Jackson's Wanna Be Startin' Somethin', and declared that the company would "change the world again".

More than 13,000 Microsoft employees had queued to be a part of the annual company-wide event.

The firm has not yet announced a replacement chief executive.

Mr Ballmer will retire within the next year and will leave the company in a strategically precarious position as it looks to claw back lost ground in the mobile sector.

While at the helm, he became known for his vigorous and enthusiastic presentations in which he would routinely declare his love for Microsoft and its products.

Microsoft staff took to social media to share details of Mr Ballmer's last appearance as boss at the event described as being more like a "rock concert".

It was held at the 17,000-capacity Key Arena in Seattle, a venue usually used for basketball and ice hockey.
