The result of a popular Russian TV talent show - The Voice Kids - has been cancelled after thousands of fraudulent votes were found to have handed victory to a millionaire's young daughter.

There were complaints after singer Mikella Abramova, aged 10, won with 56.5% of the phone-in vote.

She is the daughter of pop singer Alsou and wealthy businessman Yan Abramov.

State-owned Channel One TV says it will make its voting system safer, and the children will appear in a special show. A cyber security firm, Group-IB, was hired to examine the vote for Mikella Abramova, after the final of The Voice Kids, which is in its sixth season on Russian TV.
