LONDON (AP) — British oil company BP says that Anadarko Petroleum Co. has agreed to pay $4 billion to settle all claims between them resulting from the Gulf of Mexico oil spill.Anadarko held a 25 percent share in the Macondo well which blew out in April last year, causing the largest oil spill in U.S. history.BP said Monday that the cash will be applied to the British company's $20 billion trust fund to settle claims from the incident. Texas-based Anadarko is also handing over its stake in the well to BP.BP says the settlement was not an admission of liability by either party.
