ISLAMABAD: Lawyers of former chief justice Iftikhar Muhammad Chaudhry on Thursday sent a defamation notice worth 20 billion rupees to Pakistan Tehreek-i-Insaf (PTI) chief Imran Khan.

Chaudhry’s lawyers while speaking to media representatives outside the Supreme Court said Imran Khan was attempting to disparage and malign the superior judiciary.

They added legal proceedings would be initiated against the PTI chief if he failed to apologise for the allegations he had leveled earlier against the former chief justice.

Earlier, sources said Chaudhry's legal team will initiate proceedings against the PTI supremo if the latter fails to prove the allegations he has been levelling against the former chief justice.

The PTI chief had accused the former chief justice of poll rigging in the 2013 general election.

Moreover, Chaudhry's son, Arsalan Iftikhar, had recently alleged that Imran did not fulfill the criterion set for being an elected representative of the people, as described in Articles 62 and 63 of the Constitution.

Arsalan had said that there were doubts on Imran’s credibility to be elected as a parliamentarian.
