Former prime minister Nawaz Sharif Thursday lashed out at the National Accountability Bureau (NAB), saying the allegations levelled against him by the watchdog were "shameful".

Addressing a press conference in Islamabad, the PML-N supreme leader demanded the NAB chief bring forward evidence to prove the allegations against him or resign.

Regarding a question over the inclusion of Southern Punjab Province Front into Pakistan Tehreek-e-Insaf (PTI), Nawaz Sharif said that no one knew leaders of the said front.

Nawaz Sharif said those who joined PTI stood with Imran Khan while the rest of the nation was standing by Pakistan Muslim League-Nawaz (PML-N).

He added that Imran Khan was not a trustworthy politician as he had dual standards, saying a politician with dual standards has no worth.

On Tuesday, NAB Chairman Justice (r) Javed Iqbal took the notice of money laundering allegations against Nawaz Sharif . The NAB chairman ordered an investigation against former Prime Minister.
