According to Hindustan Times:
The International Cricket Council (ICC) has warned Indian captain Mahendra Singh Dhoni that he could be in breach of its ambush marketing laws and has asked him to stop promoting companies and products not related to the World Cup. Dhoni has earned ICC’s displeasure for doing advertisements for Sony and Aircel. According to the ICC’s rules, players had to stop promoting companies and products not related to the World Cup days before the event begins on February 19.
The DNA newspaper reports ICC has written a letter telling Dhoni that a recent commercial he had featured in could be in breach of its ambush marketing laws.
According to sources, the ICC has written to chief executives of all the national boards reminding them of the need for strict adherence to the ambush marketing clause after the publication of the Dhoni’s commercial in a leading national daily.
In a recent advertisement, Dhoni was seen endorsing a product that is a competition to an official sponsor of the World Cup. As per the ambush marketing rules, that is not permitted from seven days prior to the start of the championship.
