Upon being told by Malik Riaz that Imran Khan has been sending him several messages requesting him for a patch-up [with Zardari and/or the then opposition], Asif Zardari could be heard saying, "It is impossible now."
Imran Khan had been bitterly criticising the PPP co-chairperson during his public speeches. Geo reported that members of the coalition government were wondering if this was an attempt to create rifts within Pakistan Democratic Movement (PDM), or a desperate cry for help.
