For the latter, they will pick 15 from the preliminary squad revealed in July.

Opening batsman Marcus Trescothick was in that 30-man line-up but has since ruled himself out of contention, and several domestic stars could come in.

"I think there will be surprises. Our squad will contain what is perceived to be Twenty20 specialists," chairman of selectors David Graveney told the BBC.

"We played two Twenty20 games (in June) against the West Indies, we learned something from that."

Graveney watched a host of the men in the provisional squad take part in Saturday's Twenty20 Cup finals day.

Glen Chapple and Andrew Flintoff played for Lancashire but opener Mal Loye was ruled out of their semi-final defeat with injury.

James Kirtley, Matt Prior and Luke Wright featured for Sussex, while Jon Lewis led Gloucestershire to the final.

The first of seven one-dayers against India takes place at the Rose Bowl on 21 August, while the World Twenty20 begins on 11 September, with England's first game against Zimbabwe two days later.
