Over 25,000 supporters of opposition leader Imran Khan and cleric Tahir-ul-Qadri vowing not to back down till Prime Minister Nawaz Sharif resigns and dissolves Parliament and provincial assemblies, poured into the streets of Pakistan's capital, posing the biggest challenge to the 15-month-old civilian government.
Unfazed by the country's apex court's order against any unconstitutional step to topple the government, the two opposition groups held separate sit-ins, demanding Sharif's resignation and fresh polls alleging rigging during the last year's elections.
Khan, who had left the protest venue to rest at his house in Bani Gala area of Islamabad, came out later to join his supporters waiting for hours at the protest venue.
