Incredible: Shivraj Resigned. But Why?

The home minister named after the brave Maratha warrior finally resigns. I haven't seen his resignation letter, so I am curious what reasons Shivraj gave for his resignation.

But why now? We are told by the press that he has become too hot even for maharani Sonia to handle. Apparently the sleeping queen just woke up to realize that he wasn't doing his job for the past four and half years and that we have had terrorists incidents every two months for past few years killing thousands of innocent children, women, and men. Of course, the brave fellow soldiers of socialist Congress I brought out their own knifes to finish of dead body. Are we supposed to believe this nonsense!

Now the sleeping queen has new taxi driver too. That's nice. Apparently having a full time taxi driver is more important then having a full time finance minister to deal with current global financial crisis. Won't it better if Manmohan himself retained home ministry because the intelligence agencies report directly to him anyway. Also, any reformation of intelligence agencies and new agencies that would sprout from the Mumbai Islamic death cult massacre would have be handled by the prime minister and his office anyway. But surely a prime minister cannot be a full time taxi driver for the sleeping queen. The cabinet shuffle makes perfect sense.
