But the financial services sector regulator is reported to have forced a delay after raising concerns about how financially stable this deal would leave Prudential.

Outlook Tidjane Thiam knows a thing or two about coups, having been ousted from a ministerial post in the Ivory Coast government in 1999 by just such a rebellion. If he's not careful, he might find himself on the end of a similar plot courtesy of Prudential shareholders. A man whose intellect and talents were trumpeted from the rooftops on his appointment last year is rapidly beginning to look accident prone.
