A doctor who operated on Kanye West's mother Donda a day before she died has given up his medical license.

Under-fire Dr. Jan Adams was facing a litany of official complaints questioning his fitness to practice, including two drink-drive convictions and failure to pay child support.

His record also contains four malpractice judgements against him between 2001 and 2007.

But he has surrendered his license rather than fight his case, according to a Medical Board of California official.

Dr Adams performed surgery on Donda West in November 2007, but she died of heart failure the following day.

Candis Cohen, spokeswoman for the Medical Board of California, tells People.com, "A series of complaints were filed against Mr Adams, but he chose to surrender his license instead of contest them."
