The Godfather of Silicon Valley is back at the top

Its not exactly the Corleone family, but five years after clearing his name, Frank Quattrone has returned to head Silicon Valley's biggest deals.

On Monday, Quattrone was named on the ticket advising Motorola Mobility on Google's $8.8bn (£5.3bn) acquisition of the smartphone company. Three days later he was back as lead adviser to Autonomy on Hewlett-Packard's £6.7bn bid for the British technology group.
