Actor Robin Williams has been found dead in what police said was a suspected suicide at his home in California.

The 63-year-old, known for films such as Good Morning, Vietnam and Mrs Doubtfire, had been grappling with severe depression recently, according to his press representative.

In a statement, his wife, Susan Schneider, said: ''This morning, I lost my husband and my best friend, while the world lost one of its most beloved artists and beautiful human beings.''
