However, the shoes failed to reach the stage.
The shoe-thrower, who has not been identified so far, was arrested and taken away by security personnel.
Meanwhile, Minister for Information and Broadcasting Qamar Zaman Kaira has denied the occurrence of the shoe-hurling incident.

Many in Pakistan have criticised Zardari over his trip to United Kingdom given that it comes after Cameron's remarked that Pakistan was exporting terrorism while his trip to India.
