There has been a fresh demand to summon Prime Minister Manmohan Singh before the Joint Parliamentary Committee probing irregularities in the allocation of spectrum to telecom firms.
Was the prime minister aware of what was happening in the Department of Telecommunications (DoT) under A Raja?
Did he turn a blind eye to it?
The 19 letters exchanged between Dr Singh and Mr Raja give us a good idea of what was going through the prime minister's mind.
