BlackBerry manufacturer and parent RIM has revealed that its lead marketer in Europe, Sarah Probert, has left the company just three months into the BB10 campaign that many believe will make-or-break the brand's fortunes.

In a staunch defence of his company, Research In Motion chief executive Thorsten Heins says that all is well with production of the new BlackBerry and the health of the company at large.

Research In Motion, the manufacturer behind BlackBerry smartphones, is in very deep trouble as it posted a major loss, cut 5000 jobs and delayed the release of their BB10 operating system until early 2013.
