At least 300 PML-N workers and party leaders, including a Union Council chairman, vice chairman and counsellors, have been arrested in a crackdown in Lahore as the city braces itself to receive ousted premier Nawaz Sharif and his daughter Maryam Nawaz on Friday.

Additionally, in order to "maintain law and order" in the city, 10,000 police officers will be deployed across Lahore on Friday.

The Anti-Riot Unit will be on alert, and the Dolphin Squad and the Police Response Unit will be deployed to sensitive areas of the city.

Containers will be set up on tonight in order to block main thoroughfares across the city, while all roads leading to the airport will be sealed, according to the Lahore Traffic Police.

PML-N President Shahbaz Sharif is expected to lead a rally to Lahore's Allama Iqbal International Airport to receive Nawaz and Maryam as they return from London.

PML-N Spokesperson Marriyum Aurangzeb in an earlier press conference claimed it would be "a historic reception", with "tens of thousands of people" gathering in Lahore to welcome the father-daughter duo in a peaceful rally.
