Zurich - Jacques Aigrain, the head of Swiss Re, the world's second largest re-insurer which suffered huge losses in 2008, has resigned his post, the company announced Thursday. He will be succeeded by current deputy CEO, Stefan Lippe.

Lippe, a German national, has been with Swiss Re for 25 years.

Earlier this month, the re-insurer said it had managed to raise capital, including a 3 billion-Swiss-franc (2.58 billion dollars)- investment from US financier Warren Buffet.

The group was considering taking another 2 billion from other investors.

The capital was needed in light of losses over 2008 reaching a whopping 1 billion francs, with the company now struggling to maintain its AA credit rating.

Swiss media said the company hoped to boost confidence with the resignation of Aigrain, who will stay on in a transition role until the
18th of this month. The company's stock has dropped 62 per cent since the start of the year. (dpa)
