Thousands of PTI activists thronged Lahore's Liberty Chowk on Friday afternoon for the commencement of the long march, dubbed 'Haqeeqi Azadi March' by the party.
Many more are expected to join a convoy that will travel around 380 kilometres from Lahore to Islamabad over the next week, stopping along the way to hold rallies and gather more protesters.
It will pass through Ferozepur Road, Icchra, Azadi Chowk, Mozang, Data Darbar side, and Muridke. It will enter the Islamabad after passing through Kamonki, Gujranwala, Daska, Sumbrial, Lala Musa, Khariyan, Gujjar Khan and Rawalpindi.
It is expected to culminate in the Pakistani capital on November 4.
The march started moving only late on Friday afternoon, delayed by several hours.
