As mudslinging between the ruling party and opposition PTI reached an all time high, outspoken Pakistan Muslim League-Nawaz leader Senator Mushahidullah Khan on Friday said he was shocked by Pakistan Tehreek-e-Insaf Chairman Imran Khan's allegation that his supporters were not being permitted to bring food to the chief's residence at Bani Gala.

"No such instructions have been given to the police," the PML-N leader told Geo adding, "if instructions have been given, they have been told to stop cocaine from being brought in."

"No cocaine will be allowed to go at any cost. No narcotics will be allowed to reach any person as it is unlawful. Any time Imran Khan needs food, Islamabad police have been instructed to supply him the complete food that he consumes... whether it is the sympathy of people, deer meat or desi chicken."

The senator's comment is an apparent accusation against the PTI leader who has vowed to lock down the capital and prevent the government from functioning.

Mushahidullah has also made some personal attacks on opposition leaders, particularly Imran Khan, in the past while he defended the prime minister from accusations that he is hoarding wealth offshore.

He has termed Imran Khan “the founder of offshore companies”, and said the opposition was demanding accountability of Prime Minister Nawaz Sharif and Punjab Chief Minister Shahbaz Sharif despite the fact that the Panama Papers did not contain their names.

He said that the names of former prime minister Benazir Bhutto, Rehman Malik, Imran Khan, Jahangir Tareen and Aleem Khan had appeared in the Panama Papers instead.

Praising Mr Sharif in the past, Mushahidullah has declared that no one could cause any damage to him. “These people cannot compete with Nawaz Sharif. They want to enter the power corridor through the backdoor and negative tactics. First you need to clean your black faces and hands,” he said.

While speaking to reporters outside his residence in Islamabad, Khan said he had been placed under virtual house arrest and Islamabad police forces were not even allowing food to be brought to his house.

Police deployment outside Bani Gala began early Friday, as the government took measures to ensure that a rally of Awami Muslim League Leader Sheikh Rasheed, which Imran Khan was due to make an appearance at, did not proceed.

The government claimed that it was taking action against the PTI for violating a ban that prohibited assembly of four or more persons imposed under Section 144 of the criminal procedure code.

PTI activists had also taken positions in front of Khan's residence. A PTI volunteer earlier claimed that around 2,500 party workers have already reached Bani Gala.

"Whenever he wants food, the Islamabad police has been instructed that it should be provided," Mushahidullah said.

Referring to PTI chairman, he said 'these leaders are operating with a hidden agenda, these leaders are the enemies of Pakistan's success."

He added, "Pakistan's prosperity is fast reaching it's destination under the leadership of Nawaz Sharif."
