Vodafone chief executive Arun Sarin has been hit by a further blow following the decision by European head Bill Morrow to quit the mobile group to return to the US. His exit comes as investors with over 10% of the company are expected to abstain or vote against Sarin's re-election tomorrow.

Shareholders are angry with the global strategy pursued by Sarin, recent boardroom upheaval and the poor performance of the share price.
