England, Australia and India have delayed signing a contract because of a possible conflict with personal sponsors.

ICC chief executive Malcolm Speed sent a statement to national cricket boards saying it would not tolerate any infringement of the deal with sponsors.

He said the ICC was aware of possible "ambush" marketing plans by companies not officially signed up as partners.

"Every major sporting event provides protection to their partners and anyone else involved in elite sport would recognise that this is an essential component of being able to stage these events," Speed said.

On Monday, the Board of Control for Cricket in India said it had to delay naming its squad because contracts had not been signed.

Leading Indian stars such as Sachin Tendulkar and Sourav Ganguly endorse a vast number of products which could contravene the terms of the ICC contracts.

"I am not announcing the team as our players have still not signed the ICC contract, which is required to be signed by all those selected for the event," Niranjan Shah secretary of the BCCI said.

Australia and England have also yet to sign the contract which forbids players to have anything to do with rival companies for a month either side of the tournament which runs from 12-30 of September.

David Graveney, England's chairman of selectors said: "The problem leaves the players in a difficult situation whereby they would be in breach of existing contracts."
