Embattled BP CEO Tony Hayward said Sunday that he intends to remain in his current position.

Hayward has faced calls to step down since an explosion occurred on a rig in the Gulf of Mexico his company was leasing six weeks ago, causing a massive oil spill. 

"I have absolute intention of seeing this through to the end," Hayward said on BBC's "Andrew Marr Show."

President Barack Obama, members of Congress and other officials have pressured BP to do more in the response effort. Obama has called the spill the worst environmental disaster in U.S. history.

BP has also been accused of not being adequately prepared to face a spill of this magnitude.

Coast Guard Adm. Thad Allen, the national incident commander, said Sunday progress is being made in the cleanup effort, but that he will not be satisfied as long as oil is in the water.

Hayward said his company is committed to the cleanup effort.

"I think everyone in BP is devastated and heartbroken by this. I am and everyone in BP is," he said. "And everyone in BP is determined to do the right thing to make this right, and that is stop the spill, clean it up, remediate the environmental damage and make good the livelihoods of the people of the Gulf Coast."
