Sir Donald Bradman's son has filed a law suit against a firm that allowed Bradman’s name to be used to sell biscuits in India.

John said that his father's identity is not "a brand name, like Mickey Mouse".

John is seeking, on behalf of the executors of the late Sir Donald's estate, unspecified financial damages from Allens Arthur Robinson for failing to take "due care, skill and diligence" in licensing use of The Don's name for commercial purposes, The Australian reports.

"John has accused the law firm of using his father's identity as a brand name, like Mickey Mouse," the report said.

Letters tabled by Bradman's family in Supreme Court revealed Bradman was unaware of the monetary value of his name, and show the cricketing great was concerned about the control of his estate.
