"Pietersen had wished to play in to the T20 World Cup - but his England contract states he must be available for both formats or neither."
Got that from the Lords twitter account, seems like a lack of common sense from the ECB. I doubt the ECB will sit still and do nothing, because the last thing you want before a 20/20 world cup is to see your best batsmen who scored a century in the IPL retire..
FvanN - Chris Gayle doesn't play tests does he? His last one was in 2010..
The ECB ideally should give Pietersen a new contract which states that he should ONLY play the limited overs games, because that's what he is suited to and ideally he should be moving out of the test team to create space for a new, younger batsmen.
