Tony Hayward is on the verge of leaving BP, according to sources

The BP has decided that its chief executive Tony Hayward must leave office because of his handling of the spill, and his departure will probably be announced within 36 hours, officials said Sunday, sources close to the group.

The board of BP is due to meet Monday to determine how the departure of Hayward and its replacement by Bob Dudley, the American leader who also oversees the fight against the oil spill, sources said.

Replace Hayward at this stage of operations could be difficult for BP.Well Macondo, which lets out of oil since the explosion of the platform Deepwater Horizon April 20, has not yet been definitively blocked.

If problems occur during the recent operations, Dudley's reputation could also suffer.

But the fact that the leak has been controlled for over a week by a temporary containment has led the company to be more concerned about the future of its chief executive.

According to sources, Hayward acknowledged that he was in the interests of BP let him go.

The British oil giant has lost 40% of its stock value since the beginning of the disaster.The group would not comment on rumors of departure from Hayward, declaring that he was general manager with the full support of the board of directors.

A spokesman for BP declined to repeat the news last week that the board does not even discussed the future of Hayward.

In the Gulf of Mexico, ships trying to stop the leak came back Sunday on the site after being forced to move away from threats of Tropical Storm Bonnie, now dissipated.

The next step is now the operation known as "static kill", which is to inject heavy fluids and cement into a pit pass.

This operation could begin in three to five days, according to Coast Guard Admiral Thad Allen, who directs operations for the U.S. government.
