Thank you guys for all your help. Just called this morning to CRO and now I am going to extend my ARD to 24/03/10 and prepare accounts 24/06/08 to 30/06/09.
Notwithstanding that the CRO told you to do this, my understanding is that you CANNOT extend an ARD from 2009 into 2010.
You will still need to file a return with an ARD of 24/12/2009
