1306 GMT [Dow Jones] BP (BP.LN) is +4.2% at 335p, rising to the top of the FTSE 100 gainers. It leap-frogs Marks & Spencer (MKS.LN), +2.3% at 341p, which was leading the upside earlier. This follows reports that BP is looking for sizeable investors, likely in the Middle East, to take an investment in the company. The reports come as the cost of the Gulf of Mexico response is now over $3B. Meanwhile, a Libyan oil official tells Zawya Dow Jones that Libya should buy a stake in the company. A trader says it must be remembered that Wall Street is closed Monday, and therefore it may be free from the aggressive selling it has witnessed of late.
