India are refusing to unveil their squad for the Champions Trophy amid speculation they might pull out because of a row with the sport's governing body over revenue sharing.

The powerful Board of Control for Cricket in India (BCCI) has already missed the agreed April 25 deadline for naming their squad for the eight-nation event beginning in England and Wales on June 1.

The other seven nations have named their squads but India are unlikely to face any sanction from the International Cricket Council (ICC) under the rules of the 50-over tournament.

India's reluctance stems from their long-running opposition to changes in the financial and governance structure of the ICC which would reduce their influence and earnings along with the other members of the so-called "big three" Australia and England.

The dispute has raised speculation in India that the cricket-mad nation could pull out the 50-over Champions Trophy tournament, an event they won in 2013, an option the BCCI was not ruling out.

"It is too early to make predictions since the event is more than a month away, but nothing can be ruled out. Let's wait and watch," a BCCI board official told.
