PTI spokesperson Naeemul Haq said the party will challenge the warrant in the Islamabad High Court, Dawn news reported.
"We have made a decision to challenge the ECP order today because it is illegal and the commission has no jurisdiction to issue any arrest warrants for a political leader", Khan's spokesman Naeemul Haq told Anadolu Agency.
The ECP has ordered that the PTI chairman be arrested and brought to the next hearing of the case filed by PTI dissident and one of the party's founding members, Akbar S. Babar, on October 26.

Talking to media men outside the Supreme Court on Wednesday, he said Imran Khan was running away from judicial proceedings and was not appearing before the courts.
The cricketer-turned-politician had accused the ECP of being biased in the foreign-funding case following which his counsel had tendered an apology with the commission. This warrant has been issued for failing to appear in the court repeatedly and not giving a written justification or apology to the court for not appearing despite various letters. "We will also look into whether this is contempt of the IHC's full bench or not, and then (the party) we will challenge it".
While in his previous hearing, the PTI Chief has submitted his reply through his lawyer, "I respect the ECP and believe in the supremacy of institutions".
