Asif Zardari said his wife, who was assassinated Thursday, had left written instructions on how her political party should move forward in the future, the Press Trust of India reported.
"She has left a message for the party and she has left a will and we will make it public tomorrow," Zardari said.
"We have called for a meeting and her will will be read out there and the instructions she has left will be read out there."
Zardari, who also detailed the impact the loss of his wife has had on him personally, said he would consider succeeding her as the head of the PPP given the right circumstances.
"It depends on the party and depends on the will," he said.
