ISLAMABD: Pakistan Tehirk-i-Insaf (PTI) chief Imran Khan on Monday postponed a scheduled press conference following a clash between two groups of his party at the party secretariat.

Khyber Pakhtunkhwa Irrigation Minister Pervez Khatak was due to announce his decision to join PTI in the press conference with Imran Khan.

The supporter of Khatak and his opponents, headed by PTI Nowshera chief Sajid Gumryani, clashed with each other at the PTI central secretariat.

Two groups freely threw eggs, chairs and other office equipments at each other.

Party workers from Nowshera had serious reservations at joining of Khatak. Angry workers said there was no place for old and corrupt people in the PTI, which was claiming to bring about change with youth and new faces.

Police also reached the scene and safely rescued the provincial minister.

After the clash, Khan postponed his scheduled press conference and set up a committee to investigate the incident.
