ISLAMABAD, Aug. 27 (Xinhua) -- An opposition party, which has been protesting against Prime Minister Nawaz Sharif since August 14, on Wednesday said it is halting talks with the government in a move that may further deepen the country's political crisis.
Tehrik-e-Insaf leader Imran Khan told his supporters in the national capital that he is stopping the talks and will press for the resignation of the prime minister.
A government team held talks with Khan party's leaders late Tuesday; however no progress has been made due to the issue concerning Sharif's resignation.
"No more dialogues with the government unless Prime Minister Nawaz Sharif resigns," Khan said while addressing his party's activists who have staged a sit-in for near two weeks.
Khan is campaigning for the resignation of the prime minister as he claims that he was elected through "rigged elections" last year.
The government has rejected Khan's claim, but the prime minister has promised a judicial enquiry into the allegations.
Khan has refused to accept the judicial enquiry under Nawaz Sharif, saying no independent inquiry is possible "under PM Nawaz Sharif."
"Demand of resignation of the prime minister and re-elections are our democratic demand," he added.
A religious leader, Dr Tahir ul Qadri, is also leading a protest sit-in in Islamabad against the government and wants to bring out a "revolution."
He is also demanding registration of murder cases against the prime minister and 20 other senior officials, including ministers and police officers, for the killing of his nearly 16 supporters in police firing in June.
A court has ordered registration of murder cases against the prime minister, interior minister, chief minister of Punjab province and some other ruling party leaders. However police have not yet registered the cases.
A government team led by Finance Minister Ishaq Dar met Dr Tahir ul Qadri Wednesday to address his demands and end the protest that has disrupted life in Islamabad.
Official sources said the government negotiators are likely to present some formula to Qadri to encourage him to end the protest.
Nawaz Sharif Wednesday told the parliament that protests in Islamabad has badly affected economic activities in the country, stressing that his government will not allow anyone to derail the system.
