Yesterday, It was just an announcement. Otherwise, almost everything was decided. On 24 July, Imran Khan met Dr. TUQ in Lahore (secretly). Because of some political reasons, they announced it now. However both have different agenda but they did agree on a common point i.e to remove present govt.
Now, I think, they don't have to sit too long to achieve their goal. As it is already been 5 days, and still the whole country is contained by containers.
I believe, Qadri has more clear and realistic agenda than IK. However, some people say that everything should be done under constitution. Actually, certain amendments will be required to fulfill either khan's or Qadri's agenda. Hopefully, both knows it. And Imran Khan would not want to say it again "hum se ghalti ho gai".

Ya Allah Khair
