The estranged husband of Lisa Marie Presley has hit back at allegations that he held "disturbing" images of children, calling the accusations unproven and malicious.

Michael Lockwood, a musician, was accused by the daughter of Elvis of having illegal images on his computer.

"When I discovered the photos on [Lockwood's] computer, and viewed the videos, I was shocked and horrified and sick to my stomach," she wrote in court documents.

The couple's eight-year-old twin daughters, Harper and Finley, are currently in care in California. Ms Presley told the court she is living in the home of her eldest daughter, model and actress Riley Keough, 27.
