Now, solve this: Verify if the sentiment of the following document towards the entity Tony Hayward is Negative . Robert Dudley  who will replace Tony Hayward on Oct. 1  promised changes in light of the environmental disaster. "There's no question we are going to learn things from this investigation of the incident " he said.
 Hayward has some sympathy in his native Britain  where many pensions rely on BP stock and some consider U.S. outrage at the company to be over the top. A recurring theme in newspaper editorials and discussions among many Britons is that there simply wasn't much one man could do in the face of relentless American wrath.
 "BP sends Tony Hayward to Siberia to appease US " read a headline in the Guardian.
 Hayward  who will stay on BP's board until Nov. 30  will receive a year's salary of 1.045 million pounds (US$1.6 million) as part of his severance package. His pension benefits are valued at about 11 million pounds (US$16.8 million)  and he retains his rights to shares under a long-term performance program that could eventually be worth several million pounds if BP's share price recovers.
 Hayward said it was right that BP embark on its next phase under new leadership  and expressed his condolences for the families of the workers killed in the explosion.
 "The Gulf of Mexico explosion was a terrible tragedy for which -- as the man in charge of BP when it happened -- I will always feel a deep responsibility  regardless of where blame is ultimately found to lie " he said.
 President Barack Obama  who once said he would fire Hayward if he could  discussed the change in BP's leadership with Svanberg on Monday  Gibbs said Tuesday. No details about the conversation were released.
 Dudley spent some of his childhood in Mississippi and worked for 20 years at Amoco Corp.  which merged with BP in 1998. He lost out to Hayward on the CEO slot three years ago.
Hayward if he could  discussed the change in BP's leadership with Svanberg on Monday  Gibbs said Tuesday. No details about the conversation were released.
 "Our concern is not who heads BP " Gibbs said. "Mr. Hayward is leaving. The key is that BP can't leave and should not leave the Gulf. ... They have obligations and responsibilities as the responsible party in this instance that have to be met regardless of who the CEO is."
