LAHORE, Pakistan -- Pakistan's main opposition party says authorities have arrested a leading party figure, Rana Sanaullah Khan, after claiming they found drugs in one of his vehicles on a highway.
A spokeswoman for the Muslim League party, Uzma Bukhari, said Khan was arrested Monday.
He is the head of the league's branch in the eastern Punjab province.
The latest development came days after Pakistan's major opposition parties met in the capital, Islamabad, vowing to bring pressure against Prime Minister Imran Khan to step down for his alleged failure in handling the country's economic crisis.
Rana Sanaullah Khan is a staunch supporter of the former Prime Minister Nawaz Sharif who is currently serving a jail term on corruption charges.
