Yahoo, the once all-conquering internet giant which has in recent years stumbled from crisis to crisis, faces legal action unless it fires its chief executive by a shareholder-imposed deadline today.
The extraordinary ultimatum came after it was alleged that Scott Thompson, whom Yahoo poached from eBay just four months ago, had lied on his CV by inventing a computer science degree that his university never offered.
After initially dismissing the issue as an "inadvertent error", Yahoo is now engaged in a frantic review of why Thompson was claimed to have two degrees - one in accounting, the other in computer science - from Stonehill College, the Catholic university near Boston where he graduated in 1979.
Its computer science course did not start until 1983.
The two degrees have appeared on the executive's resume periodically as he has built a career in the technology sector that took him to the helm of eBay's subsidiary PayPal and then to Yahoo in January.
