"Imran Khan said he will take oath as Prime Minister on 11th of next month," reported Radio Pakistan.

Pakistan voted to elect a new Prime Minister last week.

Khan and his PTI scripted a massive victory in the polls.

Meanwhile, Afghanistan President Ashraf Ghani on Sunday spoke to Khan and invited him to visit Pakistan.

"I just spoke to @ImranKhanPTI and congratulated him on the victory in parliamentary elections. We both agreed to overcome the past and to lay a new foundation for a prosperous political, social and economic future of both countries #Afghanistan and #Pakistan," Ghani tweeted.

Inviting Imran Khan, Ghani said: "I extended an open invitation to Mr. Khan and he expressed his wishes to visit Kabul soon."
