PwC, the world’s biggest accountancy firm, is making a move into the world’s worst failed state. Somalia’s interim government has asked PwC to bring bookkeeping discipline to a country where lawlessness has reigned for nearly two decades.

At the demand of international donors, the besieged government has asked PwC to set up money tracking systems to ensure that aid sent to Somalia, including $67m (€48m, £41m) pledged in April, is spent as intended and not stolen by corrupt officials.
