Islamabad [Pakistan], May 27 (ANI): Pakistan Tehreek-e-Insaf (PTI) leader and Imran Khan's close aide, Babar Awan, on Friday, departed for London amid ongoing unrest within the party, reported Geo News.

Several prominent leaders decided to part ways with PTI and said they are leaving politics.

However, Babar Awan defended himself and added by saying that his visit to London was "pre-planned".

The Islamabad High Court on Thursday ordered the release of Pakistan Tehreek-e-Insaf (PTI), Ejaz Chaudhry declaring his arrest under MPO (Maintenance of Public Order) as unlawful.
